ExcelBand 3-Color Pre-Stained Protein Ladder, Broad Range, PM5200, 500ul/Pack

Our 3-color Pre-Stained Protein Ladder (Cat# PM5200) is a broad range, ready-to-use three-color protein marker 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 in our prestained protein standard 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). SMOBio PM5200 broad ranged 3-color Pre-Stained 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, PM5200 ExcelBand 3-color Pre-Stained Protein Ladder Broad Range resolves 15 major bands in SDS-PAGE (Bis-Tris gel, MES buffer) and after Western blotting to nitrocellulose membrane.

Package
250ul/vial, 2 vials of 250ul. Total 500ul

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