Description Prestained Protein Molecular Weight Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on PVDF, nylon and nitrocellulose membranes and for approximate sizing of proteins (1-3). It is composed of prestained recombinant prokaryotic proteins. Prestained Protein Molecular Weight Marker is a mixture of 6 prestained natural proteins with apparent molecular weights from 20 kDa to 120 kDa. Applications 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. Features Size range – ~20-120 kDa. Ready-to-use – supplied in a loading buffer for direct loading on gels. Quality Control Tested in SDS-polyacrylamide gel electrophoresis and Western Blotting. Storage Buffer 62.5 mM Tris-HCl (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1.5 mM NaN3 and 33% glycerol. 友情提示:本公司产品仅用于生命科学研究实验,不作为任何药物及其他用途。 |
