Answer:
Please look at the explanation section.
Explanation:
1) To calculate the yield of a protein in the purification step, the amount of protein produced must be divided by the amount of protein produced in the first step. The expression is as follows:
%protein yield = (Amount of protein/Amount of protein produced in the first step) * 100
If you have the purity percentage and the amount of protein produced, this formula could be used:
%protein yield = (Protein amount * Purity Percentage)/100
2) If this process begins with a cell culture and ends with the purification of Ni+2NTA. One method of increasing performance is to decrease the number of steps in the purification process. Because unfortunately, at each step of the purification of a protein leads to the loss of them.
