Prestained Protein Ladder

The Prestained Protein Ladder is a three-color protein standard with 12 prestained proteins covering a wide range molecular weights from 10 to 245 kDa. The Prestained Protein Ladder is a three-color protein standard with 12 prestained 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 Pre-Stained Protein Ladder is designed for monitoring protein separation during SDSpolyacrylamide 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.
