Skip to content The BlueRAY Prestained Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range molecular weights for 10 to 180 kilodalton (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-polyacrylamide gel electrophoresis (SDS-PAGE) with Tris-glycine-SDS running buffer. The BlueRAY Prestained Protein Ladder is designed for monitoring protein separated during SDS-PAGE, verification of Western transfer efficiency on membranes (PVDF, nylon or nitrocellulose) and for approximate sizing of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heats, dilute, and add reducing agent before loading.
Features
Broad range: 10-180 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
Applications
Monitoring of protein migration during SDS-PAGE.
Monitoring of protein transfer onto membranes during Western blots.
Sizing of proteins on SDS-PAGE gels and Western blots.
