Thermo Scientific Spectra Multicolor High Range Protein Ladder is a mixture of eight blue-, green-, and orange-stained proteins (40 to 300 kDa) for use as size standards for high-MW proteins in gel electrophoresis and western blotting. The protein ladder 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.
Applications • Monitoring of protein migration during SDS-PAGE • Verifying western transfer efficiency • Approximate sizing of proteins on SDS-polyacrylamide gels and western blots • Locating a protein of interest for excision from an unstained preparative gel
