When you use methods such as Solvent precipitation, you precipitate a protein molecule but this protein molecule normally does not have the same structure as that of protein in a solution (for example disulfide bonds do not connect the same amino acids) and it is not easy to change this to that of original structure even when the same solution is present. The percent of recovery means the percent that these denatured protein molecules can gain the same structure that they have in the solution before precipitation.

What is a salt cut in protein purification?
A salt cut in protein purification is a process to reduce the concentration of salt ions in solution. This is generally done by adding a determined amount of a solution with a lower amount of salt to the sample in order to achieve an specific salt. This is typically done before an ion exchange step.
Which of the major physical laws of chemistry does the percent recovery test?
solubility
What chemical complex is eukaryotic chromosomes are composed of a complex of 60 percent protein and 40 percent DNA?
Chromatin
Why 75 percent ethanol is used in rna extraction?
to precipitate protein.
Nutrient that makes up more than 50 percent of your body weight?
Protein
What does protein expression and purification mean?
Protein expression means to clone compounds. Purification is the cleaning process of those compounds. http://en.wikipedia.org/wiki/Protein
Does total activity increase or decrease during protein purification?
Total Activity almost always decreases during protein purification.
Is protein expression and purification a scientific process?
Yes, you are correct. Protein expression and purification is definitely a good example of scientific process.
What is fold purification in protein purification?
A measure of how much more pure your protein is after a purification step in comparison to the crude. You can calculate this by dividing the purified steps specific activity by the crude steps specific activity.
Why you are adding gst tag to the protein during protein purification?
You have many proteins in a mixture. To identify a single protein you add a GST tag. So, when you are doing any further purification you will end up with your protein of choice.

What are the benefits of protein expression and purification?
Protein expression and purification is when proteins are taken and isolated for their individual benefits and then used in many products such as enzymes and in creams. The benefits are that the products they are used in are more natural and have a better balance with the body.
The PI of protein is 9.24 At what PH MY protein binds to the column and which type of column have to use for purifification?

What is 80-90 percent of protein?
80-90 percent of protein = -10
What occurs when 50 percent of a protein produces a different phenotype than that produced by 100 percent or 0 percent of the protein?
incomplete dominance
