ExcelBand™ 3-color High Range PreStained Protein Marker, 2x 250 uL/Pack
Protein Marker PM2600, PM2611 from SMOBIO, ExcelBand 3-color High Range Protein Markers, are ready-to-use 3-color protein ladders with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in Bis-Tris (MES) buffer).
Proteins in this Prestained Protein Marker PM2600 and PM2611 are covalently coupled with a blue chromophore except for two reference bands: 25 kDa green band and 75 kDa red band when separated on SDS-PAGE (Tris-Glycine buffer).
The SMOBIO 3-color Pre-Stained Protein Marker PM2600, PM2610 are 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.
Protein Marker PM2610 is produced for harsh buffers used in Western Blotting application. Prestained proteins in this enhanced product version have more quantity than those in regular PM2600. You will see strong bands in enhanced PM2610 protein marker.
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).
Under suggested conditions, PM2600 ExcelBand™ 3-color High Range Protein Marker resolves 12 major bands in 15% SDS-PAGE (Tris-Glycine buffer) and after Western blotting to nitrocellulose membrane.
