Description 

The PM5200 3-color Pre-Stained Protein Ladder Broad Range is a ready-to-use three-color protein standard with 15 pre-stained proteins covering a wide range of molecular weights from 5 to 245 kDa in Tris-Glycine Buffer (3.5 to 235 kDa in Bis-Tris (MOPS) buffer and Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with three reference proteins carrying enhanced intensity corresponding to a blue band at 20 kDa, green at 40 kDa, and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The PM5200 3-color Pre-Stained Protein Ladder Broad Range 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.

  • Three reference bands — 75 kDa (red), 40 kDa (green), and 20 kDa (blue)


Contents 

Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol). 


Quality Control

Under suggested conditions, PM5200 ExcelBand™ 3-color Pre-Stained Protein Ladder Broad Range resolves 15 major bands in SDS-PAGE (Tris-Glycine, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane. 


Storage

4°C for 3 months
-20°C for long term storage
