10-245kda Prestained Protein Ladder

We are engaged in manufacturing and exporting excellent quality 10-245kDa Prestained Protein Ladder to our valuable clients.
Size: 500 I l

a c 3 I l or 5 I l per loading for clear visualization during electrophoresis on 15 well or 10 well mini-gel respectively.
a c 1.5~2.5 I l per well for general Western transferring.
a c Apply more for thicker (> 1.5 mm) or larger gel.

The10-245kDa Prestained Protein Ladderis a three-color protein standard with 12 pre stained proteins covering a wide range molecular weights from 10 to 245 kDa. 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). The 10-245kDa Prestained Protein Ladderis 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. The ladder is supplied in gel loading buffer and is ready to use.

Contents:
Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Trisphosphate, pH 7.5 at 25A C), 2 % SDS, 3.6 M Urea,1 mM 2-Mercaptoethanol, and 15 % (v/v) Glycerol).
