SDS gel electrophoresis can be used to determine:
A) whether subunits in a protein complex are identical or not.
B) the molecular mass of a native protein complex.
C) the overall charge on a polypeptide.
D) the molecular mass of denatured protein subunits.
E) none of the above.

Question

Quizplus · Accepted Answer

SDS gel electrophoresis works by denaturing proteins and giving them an overall negative charge due to the binding of SDS molecules. Therefore, it is used to determine the molecular mass of denatured protein subunits.
