The Tri-Color Prestained Protein Molecular Weight Marker is a three-color protein standard with 10 prestained proteins covering a wide range molecular weights from 10 to 180 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green band at 25 kDa and one red band at 75 kDa when separated on SDS polyacrylamide gel using Tris-Glycine buffer). The Tri-Color Prestained Protein Molecular Weight Marker is designed for monitoring protein separated during SDS-PAGE, for verification of Western transfer efficiency on membranes (PVDF, nylon or nitrocellulose) and for approximate sizing of proteins. The Tri-Color Prestained Protein Molecular Weight Marker is supplied in gel loading buffer and is in ready to use format. No need to heat, dilute, or add reducing agent before loading.
Usage Information:
-
3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively
-
Apply more for thicker (>1.5 mm) or larger gel.
