Protein Marker PM2500 ExcelBand™ 3-color Regular Range Protein Ladder, 2x 250 uL

Protein Marker PM2500 SMOBIO ExcelBand 3-color Regular Range Protein Marker is a ready-to-use three-color 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 10 to 180 kDa Bis-Tris (MES) buffer).

Proteins in Protein Marker PM2500 are covalently coupled with a blue chromophore except for two reference bands (one green 25 kDa and one red 75 kDa band respectively) when separated on SDS-PAGE (Tris-Glycine buffer).

SMOBIO ExcelBand™ 3-color Regular Range Protein Ladder 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.

Contents
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, Protein Marker PM2500 ExcelBan 3-color Regular Range Protein Marker resolves 10 major bands in 15% SDS-PAGE (Tris-Glycine buffer) and after Western blotting to nitrocellulose membrane.

Storage
4°C for 3 months
-20°C for 24 months
