ExcelBand™ 3-color Broad Range Protein Marker PM2700, 2x 250 uL/Pack

SMOBIO ExcelBand 3-color Broad Range Protein Marker PM2700 is a ready-to-use tri-color protein ladder with 13 pre-stained proteins covering a wide range of molecular weights from 5 to 245 kDa in Tris-Glycine buffer (3.5 kDa to 235 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer).

Proteins in this SMOBIO Protein Marker PM2700 are covalently coupled with a blue chromophore except for 2 reference bands:  25 kDa green band and 75 kDa red band when separated on SDS-PAGE (Tris-Glycine buffer).

The ExcelBand Tri Color Broad Range Protein Marker PM2700 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 0.1~0.4 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).

Quality Control
Under suggested conditions, PM2700 ExcelBand™ 3-color Broad Range Protein Marker resolves 13 major bands in SDS-PAGE (Bis-Tris gel, MES buffer) and after Western blotting to nitrocellulose membrane.
