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). 

Features

  • Two-color protein standard with 11 pre-stained 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)

Applications

  • Monitoring protein separation during SDS-polyacrylamide gel electrophoresis
  • Verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) 
  • Approximating size of proteins
