Question

Quantitatively describe the unique focusing capability of IEF and identify factors that increase resolution of proteins in IEF.

Expert Solution
Step 1

IEF stands for isoelectric focusing which is a technique used to resolve a mixture of proteins on a gel. It depends upon the isoelectric points (pI) of different proteins. A combination of IEF with SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) known as 2D (dimensional) gel electrophoresis is used widely to perform protein separation.
