SeeBlue™ Pre-stained Protein Standard (Invitrogen™)

SeeBlue Pre-Stained Standard consists of nine polypeptides that resolve into sharp, tight blue bands in the range of range of 4–200 kDa allowing you to easily monitor protein electrophoresis and western transfer efficiency. The protein standard is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.
