The PM1500 ExcelBand™ All Blue Regular Range Protein Marker is a blue protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 10 to 180 kDa in Tris-Glycine buffer (9 to 170 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore, and two reference bands (at 25 kDa and 72 kDa, respectively) are enhanced in intensity when separated on SDS-PAGE (Tris-Glycine buffer).

Features

  • Blue protein standard with 10 pre-stained proteins
  • Approximately 0.1~0.5 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol)

Applications

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