Is SDS a reducing agent?

SDS will bind to the protein causing it to unfold, whereas the reducing agent will reduce the intramolecular and intermolecular disulfide bonds. Separation of proteins by SDS-PAGE is an excellent technique for producing individually "purified" proteins.

What is the function of sodium dodecyl sulfate SDS in SDS PAGE?

A very common method for separating proteins by electrophoresis uses a discontinuous polyacrylamide gel as a support medium and sodium dodecyl sulfate (SDS) to denature the proteins. The method is called sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).
