产品描述

Thermo Scientific Spectra Multicolor High Range Protein Ladder is a mixture of eight (8) blue-, green-and orange-stained

proteins (40 to 300kDa) for use as size standards for high-MW proteins in gel electrophoresis and Western blotting. Features of Spectra Multicolor High Range Protein Ladder: • Size range—eight proteins spanning 40 to 300kDa • Multicolor—three different colors for unambiguous band-size assignment • Ready-to-use—supplied in a loading buffer for direct loading on gels; no need to boil • Sharp bands—color-coded bands of similar intensity for easy visualization • Quality tested—each lot evaluated by SDS-PAGE and Western blotting • Membrane-compatible—colored bands transfer to membranes for Western blotting

Includes: • Dye-stained proteins in 62.5 mM Tris-H3PO4 (pH 7.5 at 25°C), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3 and 33% glycerol.

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
