ExcelBand 3-Color Pre-Stained Protein Marker, 10 kDa ~ 180 kDa, PM5000, 500ul/Pack

Our ExcelBand 3-color Pre-stained Protein Marker (Cat# PM5000) is a regular range, ready-to-use three-color protein marker with 13 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 in this pre-stained protein marker 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 PM5000 ExcelBand 3-color Pre-Stained Protein Marker Regular 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.

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, PM5000 ExcelBand 3-color Pre-Stained Protein Marker Regular Range resolves 13 major bands in 15% SDS-PAGE (Tris-Glycine 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

Shipping cost
The shipping cost for each order placed is $6.50, but will be automatically waived at checkout on orders of $200 and up.
