BLUelf Prestained Protein ladder

The BLUelf Prestained Protein Ladder is a three-color protein standard with 13 pre-stained proteins covering a wide range molecular weights from 5 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 BLUelf Prestained Protein Ladder 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. The protein ladder is supplied in gel loading buffer and is ready to use.

Special Features:

• Wide range: 5 to 245 kDa
• Reference Bands: One Green at 25 kDa, one Red at 75 kDa
• Ready to Use: Supplied in loading buffer for direct loading on gels
• Clear Bands: 13 sharp bands in three color protein standard for easy visualization
• Quality control: Tested on lot-to-lot basis to ensure consistent product quality
