Protein Denaturation
medium

A researcher is preparing a sample of bovine serum albumin (BSA) for a protein quantification assay. During the preparation, they accidentally expose the sample to high temperatures and strong agitation. What is the most likely consequence of these conditions on the BSA sample, and how should the researcher proceed to ensure accurate results?

Choose AnswerChoose the Best Answer

A

The BSA will denature, resulting in inaccurate quantification; the researcher should cool the sample and minimize agitation.

B

The BSA will remain stable, ensuring accurate quantification; no changes are needed.

C

The BSA will denature, but it will not affect the quantification method; standard procedures will suffice.

D

The BSA will denature, but the researcher can compensate for this by adjusting the assay conditions.

Understanding the Answer

Let's break down why this is correct

Heat and vigorous shaking break the weak bonds that keep BSA folded. Other options are incorrect because The idea that proteins never change is wrong; Denaturation does affect how the protein reacts in an assay.
