ExcelBand Pink Blue Protein Marker
250 µl x 2
The PM2400 ExcelBand Pink Blue Protein Marker is a two-color protein standard with 11 pre-stained proteins covering a wide range of molecular weights from 10 to 175 kDa in Tris-Glycine buffer (10 to 165 kDa in Bis-Tris (MOPS) buffer and 7 to 165 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a pink chromophore except for three reference bands of blue color (at 10, 40, and 90 kDa, respectively) when separated on SDS-PAGE (Tris-Glycine buffer).
The PM2400 ExcelBand Pink Blue Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
Approximately 0.2~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5), 2% SDS, 1 mM DTT, 4.8 M urea, and 12% (v/v) glycerol).
Under suggested conditions, PM2400 ExcelBand Pink Blue Protein Marker resolves 11 major bands in 15% SDS-PAGE (Tris-Glycine buffer) and after Western blotting to nitrocellulose membrane.
