Description Spectra™ Multicolor Low Range Protein Ladder is designed specifically for small protein analysis. It is a mixture of 6 recombinant, highly purified proteins and synthetic peptides with apparent molecular weights of 1.7 to 40 kDa. The proteins are individually prestained using three different dyes. The Spectra™ Multicolor Low Range Protein Ladder is ready-to-use: no heating, further dilution or addition of a reducing agent is required before use. Features Sharp and stable colors. Multicolor – easy to track on gel. Ready to load – no need to boil. Excellent Western transfer. Quality Control Tested in SDS-polyacrylamide gel electrophoresis and Western Blotting. Applications Monitoring of protein migration during SDS-PAGE (1). Verifying Western transfer efficiency (2-4). Approximate sizing of proteins on SDS-polyacrylamide gels and Western blots. Locating a protein of interest for excision from an unstained preparative gel. Storage Stable at 4°C for up to 3 months. For long term storage, store at -20°C. Storage Buffer 62.5 mM Tris-H3PO4 (pH 7.5 at 25°C), 1 mM EDTA, 2% (w/v) SDS, 10 mM DTT, 1.5 mM NaN3 and 33% (v/v) glycerol. Spectra Multicolor Low Range Protein Ladder|正品原装,长期备有现货 |
