- Broad range: 10-245 kDa (Tris-glycine-SDS running buffer)
- Ready-to-use: supplied in a loading buffer for direct loading on gels
- Easy to identify: includes the ~25, ~75 kDa reference bands coupled with a green and a red dye
- Sharp bands
The BLUeye Prestained Protein Ladder is a three-color protein standard with 12 pre-stained proteins covering a wide range molecular weights from 10 to 245 kilodalton (kDa). Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa a nd 75 kDa respectively) when separated on SDS-polyacrylamide gel electrophoresis (SDSPAGE) with Tris-glycine-SDS running buffer. The BLUeye Prestained Protein Ladder is designed for monitoring protein separation during, 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.
