Quantity:

10-245 kDa Prestained Protein Ladder

Cat. No. PL0501                                                                     
Size:
500 μl 

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


Description

The10-245 kDa 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 10-245 kDa 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 25°C), 2 % SDS, 3.6 M Urea,1 mM 2-Mercaptoethanol,  and 15 % (v/v) Glycerol).

Quality Control

Under suggested conditions, 10-245kDa Prestained Protein Ladder resolves 12 major bands in 15% SDS-PAGE (Tris-glycine buffer) and after Western blotting to nitrocellulose membrane.

Note

The apparent molecular weight of each protein (kDa) has been determined by calibration against an unstained protein ladder in each
electrophoresis condition.
