Description
Prestained protein ladders / marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verifying of Western transfer efficiency on PVDF, nylon and nitrocellulose membranes and approximate sizing of proteins. It is composed of prestained recombinant prokaryotic proteins. Prestained Protein Molecular Weight Marker is a three-color molecular weight standard, contains 9 prestained natural proteins with molecular weights from 10 kDa to 250 kDa. It has two orange reference bands–70 kDa band and 25 kDa band
