The BLUelf Prestained Protein Ladder is a three-colour protein standard with 13 pre-stained proteins covering a wide range molecular weights from 3.5 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 ladder is supplied in gel loading buffer and is Ready-to-use. Do not heat, dilute, add reducing agent before loading.
– Broad range: 3.5-240 kDa.
– Ready-to-use: supplied in a loading buffer for direct loading on gels.
– Easy to identify: includes a 25 kDa green band and 75 kDa red band for reference.
– Sharp bands.
