Novex Sharp Unstained Protein Standard is designed for accurate and convenient molecular weight estimation of proteins during SDS-PAGE and western blotting. The standard consists of a wide range of molecular weight bands consisting of 12 proteins in the range of 3.5–260 kDa. 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.
