Discussion :: Protein Purification - Section 1 (Q.No.1)

1. 

During successful purification scheme, this may be expected that the

[A]. specific activity increases
[B]. specific activity decreases
[C]. number of proteins in the sample decreases
[D]. both (a) and (c)

Answer: Option D

Explanation:

No answer description available for this question.

No.of proteins should decrease. then only we will be left with the protein of interest.

Specific activity = protein activity/ total mg of protein present.

So as we proceed towards more purification steps, we see increase in specific activity.

Both A and C are correct.

Since specific activity is inversely proportional to the total number of protein.

Therefore as the number of protein decreases, the specific activity increases.
