Invitrogen™ BenchMark™ Pre-stained Protein Ladder

Invitrogen™ BenchMark™ Pre-stained Protein Ladder

BenchMark Pre-Stained Protein Ladder contains 10 proteins ranging in apparent molecular weight from 6 to 180 kDa for use in monitoring electrophoresis or transfer from gel to membrane in western blotting. 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.

Features

• Monitoring protein migration during SDS-polyacrylamide gel electrophoresis
• Monitoring protein transfer onto membranes after western blotting
• Sizing of proteins on SDS-polyacrylamide gels and western blots

Contents

• Two vials of 250 µl each are provided in loading buffer consisting of 50 mM Tris-HCl (pH 6.8), 5 mM EDTA, 10 mM DTT, 1% (w/v) SDS, 10% (w/v) glycerol
