Description 

The PM2510 ExcelBand™ Enhanced 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 170 kDa Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green ａnd one red band at 25 kDa ａnd 75 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). PM2510 ExcelBand™ Enhanced 3-color Regular Range Protein Marker 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.

Features

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.

• Two reference bands — 75 kDa (red) ａnd 25 kDa (green)

Contents 

Approximately 0.2~0.6 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5), 2% SDS, 3.6 M urea, ａnd 15% (v/v) glycerol).

Quality Control

Under suggested conditions, PM2510 ExcelBand™ Enhanced 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
