Measure distilled water by graduated cylinder, and move into beaker.

2. Deep hydrochloric acid is measured and taken with another beaker and added to １ little by little,

while stirred well.

※about concentration

The concentration of marketed deep hydrochloric acid (HCl35%) is 11.33N. so, if you want to make

ⅰ) 1N, you must add 88.5g of deep hydrochloric acid to distilled water and make it 1L.

ⅱ) 5N, you must add 442g of deep hydrochloric acid to distilled water and make it 1L.

ⅲ) 10N, you must add 885g of deep hydrochloric acid to distilled water and make it 1L.

3. Quit stirring, add distilled water till wished volume and stir again.

If needed, store in the reagent pot. Write the reagent name, concentration, date, and maker.

Notes

Inside the pot of deep hydrochloric acid is full of toxic HCl gas, and it spouts out when you open the pot.

So be careful not to breathe the gas and be careful to be well ventilated.

Wash down as soon as possible when the reagent sticks to skin or eye.

Be careful for generation of heat when you dilate deep hydrochloric acid. Adjust volume after cooled down.

The concentration of marketed deep hydrochloric acid is estimated one. Titrate by known alkaline when

you want to know the exact concentration.

NaOH

1. The Experimental tool what you need must be washed and dried.

Measure distilled water by graduated cylinder, and a half of them should be moved into beaker 1, and

the other should be reserved

2. Measure NaOH using a balance and a beaker 2, and add it to the beaker of 1 as soon as possible.

Dissolve beaker2-remaining NaOH by distilled water of graduated cylinder, move it into the beaker and stir up.

NaOH is 40g/mol. So if you want to make

ⅰ) 1N, you must add 40g of NaOH to distilled water and make it 1L.

ⅱ) 5N, you must add 200g of NaOH to distilled water and make it 1L.

ⅲ) 10N, you must add 400g of NaOH to distilled water and make it 1L.

3. If needed, store in the reagent pot. Write the reagent name, concentration, date, and maker.

Notes

The granular NaOH deliquesces, or absorb atmospheric water. When you use a balance, put a paper

between a beaker and a scale. Weigh as soon as possible. NaOH pot must be tightly closed at once.

Be careful for generation of heat when you dilate NaOH. Since the steam is toxic, be careful not to

breathe the it and be careful to be well ventilated. Adjust volume after cooled down.

Wash down as soon as possible when the reagent sticks to your skin or eye.

Since the size of a NaOH particle is large, you cannot weigh exactly.

Titrate by known alkaline when you want to know the exact concentration.

The scale must be used carefully. Clean up immediately when you spill any reagents.

Chapter 1 Overview of Each Machine

1-1 Introduction

As you know, PCR is one of the most useful ways for the molecular researchers because of its convenience of the method. However, no one can use the same PCR program every time as the amplification condition depends on the primers and the length of fragments amplified. So, every user must learn how to make and edit PCR program and find the best amplification condition in the experiments. There are three types of PCR machines in this laboratory, including Peltier Thermal Cycler, PCR System 9700, and Master Cycler. In this chapter, the features of each machine are explained briefly.

1-1a Peltier Thermal Cycler (MJ)
Mostly, three types of vessels, 8-well tube, 96-well plate, and 384-well plate, are used in PCR. Many PCR machines are designed for 8-well tube and 96-well plate, however, Peltier Thermal Cycler can adapt to all of the three types of the vessels by changing the unit. There are two machines and three units, including two 96-well plate adapters and one 384-well plate adapter in this laboratory. Usually, one machine mounts 96-well plate adapter, and the other mounts 384-well plate adapter. In case, both machines can equip 96-well plate adapter. Moreover, user can create gradient PCR program with Peltier Thermal Cycler. Therefore, this machine can cover almost all of the amplification conditions required in PCR experiments.

1-1b PCR System 9700 (ABI)
No special functions are equipped with PCR System 9700. The available vessels are 8-well tube and 96-well plate. “High stability”, that is the one and all features of PCR System 9700. You can see this name in a lot of literatures. This fact also suggests how many people trust PCR System 9700.

1-1c Master Cycler (eppendorf)
The red-letter feature of Master Cycler is that this machine equips CPU just like PC, followed by multi-function and user-friendly interface. Especially, the heat acceleration of Master Cycler between PCR steps is superior to other machines in this laboratory. But don’t forget to shut down the system before you cut the power for CPU!
1-2 Functional List
*
* : Conventionally, researchers must add mineral oil into the wells for the reaction mixture would evaporate and liquefy on the cold lid while heating. Heat lid function solved this problem and freed the researchers from this trouble.

H. Protocol for PCR (using ExTaq from TAKARA)

1. Take 10x PCR buffer & dNTP out from the freezer and let them thaw.
2. Put template DNA*1, PCR primers*2, buffers and other solutions necessary for reactions into PCR tubes.
The template DNA(10ng/μl) 1　 μl
PCR primers (2,5μM) 2　 μl
10xbuffer 1　 μl
dNTPs (2μM each) 1　 μl
DMSO 0.5 μl
ExTaq DNA polymerase 0.04μl
Sterilized water 4.46μl (up to 10μl)

Usually you can’t scale the 0.04μl ExTaq DNA polymerase, so what you have to do is:
1) Put DNA and Primers into each PCR tube.
2) Mix other solutions and water for all reactions in a 1.5ml eppendorf tube. If you are going to perform 10 reactions, Mix;

10xbuffer 1　 μl X 11 = 11 μl
dNTPs (2μM each) 1　 μl X 11 = 11 μl
DMSO 0.5 μl X 11 = 5.5 μl
ExTaq DNA polymerase 0.04μl X 11 = 0.44 μl
Sterilized water 4.46μl X 11 = 49.06μl

And then, you put 7μl PCR cocktail into each tube.

*1 The template DNA should be less than 10ng per 10μl final volume of PCR reaction.
*2 You can double the amount of PCR primers to get better results.

3. Start reactions with thermal cycler. The protocol attached to ExTaq says PCR cycle should be:
95℃ for 1min
↓
98℃ for 10sec
58℃ for 30sec X 30~40cycles
72℃ for 1min
↓
72℃ for 3min
But the annealing cycle(58℃ for 30sec) is actually too short for 20mer primers with which we work. You’d better set this time at least 45sec, or make your primers longer than 24 bases.
4. After setting the PCR reactions, you make 1.4% agarose gel for electrophoresis.
Put a beaker on a scale and add:

Agarose 0.7g
0.5xTBE buffer 50ml

Actually gel amount depend on which gel frame you use. Ask anybody in the lab for detail.
Put the beaker in a microwave and heat until all agarose dissolve completely and clear solution is obtained. Stir by shaking the beaker every 30 sec.

5. When PCR reaction is finished, add 1~2μl loading buffer(blue color) to each sample and load into wells.

6. Run the gel with 100V for 20-40min.

7. Check reactions by transilluminater and take pictures.

MAJOR SOYBEAN PROTEINS

2006-07-04T06:08:00.000-07:00

SOYBEAN PROTEINS

The simplest criterion used for the characterization of proteins is their solubility in various media. As in all legumes, the bulk of soybean proteins are globulins, characterized by their solubility in salt solutions. The solubility of soybean proteins in water is strongly affected by the pH. Close to 80 % of the protein in raw seeds or unheated meal can be extracted at neutral or alkaline pH. As the acidity is increased, solubility drops rapidly and a minimum is observed at pH 4.2 to 4.6. This is the isoelectric region of soybean proteins taken as a whole.
The pH dependence of solubility is used in the manufacture of isolated soybean protein, whereby defatted, unheated meal is extracted with water at neutral or slightly alkaline pH, and the protein is then precipitated from the filtered extract by acidification to the isoelectric region.
More precise and detailed fractionation of the proteins can be carried-out by techniques such as ultracentrifugation, gel filtration and electrophoresis.
Since the classical work of W. Wolff, it has become customary to characterize the soybean protein fractions by their sedimentation constants.

Four major fractions, known as 2 S, 7 S, 11 S and 15 S have been studied extensively. (S stands for Svedberg units. The numerical coefficient is the characteristic sedimentation constant in water at 20oC. The figures are not exact but nominal. Thus the 11 S globulin has a sedimentation constant of 12.3). The 11 S and 7 S fractions constitute about 70% of the total protein in soybeans. The ratio 11 S/7 S is a varietal characteristic and may vary from 0.5 to 3.

The 2 S fraction consists of low molecular weight polypeptides (in the range of 8000 to 20000 daltons) and comprises the soybean trypsin inhibitors (see below).

The 7 S fraction is highly heterogeneous. Its principal component is beta-conglycinin, a sugar containing globulin with a molecular weight in the order of 150000. The fraction also comprises enzymes (beta-amylase and lipoxygenase) and hemagglutinins (see below ).

The 11 S fraction consists of glycinin, the principal protein of soybeans. Glycinin has a molecular weight of 320000-350000 and is built of 12 sub-units, associated through hydrogen bonding and disulfide bonds. The ability of soy proteins to undergo association-dissociation reactions under known conditions, is related to their functional properties and particularly to their texturization.

The 15 S protein is probably a dimer of glycinin. Conglycinin and glycinin are storage proteins and they are found in the protein bodies within the cells of the cotyledons.

PROBLEM WITH SOYBEN PROTEIN

2006-07-04T06:06:00.000-07:00

Some of the problems associated with soybean proteins include
(1) presence of anti-nutritional factors such as trypsin inhibitor,
(2) undesirable beany flavor,
(3) elicitation of allergic reactions in susceptible individuals,
(4) poor digestibility of soybean proteins, and
(5) deficiency in sulfur-containing amino acids.

Research Plan 2005

Genetic Transformation of Soybean (Glycine max Merril L) Via Particle Bombardment
Background
The quick and best method to achieve genotype independent transformation in crops is the delivery of foreign DNA directly into regenerative cells. Micro projectile bombardment also known as particle bombardment or biolistics is presently used in researches to produce stably transformed plants in many economically important crops. It employs high velocity metal (gold or tungsten) particles to deliver biologically active DNA into targeted, published results show that embryonic or meristematic tissues are more transformable and are able to regenerate into transgenic plants. Transient gene expression can be observed in differentiated plant tissues, the expression of foreign genes is examined by visual and quantitative methods and the study of gene responsible for plant ontogeny can be possible.

Objective

The objective of the research is to improve the protein quality in soybean through particle bombardment.

IDEAS AND THOUGHTS

2006-06-30T23:12:00.000-07:00

THE STUDY OF GENES

I was born and brought up , had my education up to Higher Secondary School (grade 12) in Bhutan. I did my bachelors degree from the Institute of Agriculture and Animal sciences, IAAS, Nepal, taking Plant Breeding as elective subject. Right from my child hood I had interest in science, later in biology and then in genetics and biotechnology. The environment that I was brought up in, poverty in the hills and illiteracy among the people; made me think and work towards improvement of agriculture, increment of production and fighting against diseases, pests and weeds. Later studies made me realize that I can do much more than those. I can go deeper into the subject and try out many things which very few people want to try. I want to work with the genes, genomes and genetic transformations. I had a good influences of teachers, seniors and friends who talked about the wonders of biotechnology. Their talks were the source of my wonderment. They encouraged me to take up plant breeding as elective in the fourth year of my Bachelors (BSc. Agriculture). A key hole opened into my oppertunity. i was able to enter Kyoto University to continue my studies taking Plant Breeding as the major. Now I am working with the genetic transformation of Soybean. The title of my present research is “Improvement of Protein Quality in Soybean through Genetic Transformation”. Ref. Web: http://www.ikushu.kais.kyoto-u.ac.jp/member.html . Although I feel I have chosen a big target I am happy that have choosen it.

During my bachelors there were a few experimental works and even the practical works involved a lot of reading and writing than working. Now I understand through doing what I had learnt through reading. Everything is wonderment to me. I am working well. By March 2007 I will be awarded a masters degree. I expect to graduate with “grade A”.

I want to devote my life into the study and research of genes discovering their hidden mystery. I don’t want to limit my potential and discovery to a region or a country but I want to do a thing globally great. I expect warm suggestions and continuous encouragement from all.

Thank you
