Apparent Molecular Weight on CE-SDS and SDS-PAGE

A difference between CE-SDS and SDS-PAGE is that discrepancies in apparent molecular weight (MW) have been observed between the two methods. While CE-SDS and SDS-PAGE are typically not intended for high-resolution MW determination, many of their applications require a reasonable estimate of apparent MW. This Technical Note highlights relevant peer-reviewed publications that address these factors for comparing MW between CE-SDS and SDS-PAGE.
