The quality of the BLUeye Prestained Protein Ladder is tested on a lot-to-lot basis to ensure consistent product quality.īLUeye Prestained Protein Ladder Protocolġ. Sizing of proteins on SDS-PAGE and Western blots.Īpproximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Trisphosphate, pH 7.5 at 25☌), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol.Monitoring of protein transfer onto membranes during Western blots.Monitoring of protein migration during SDS-PAGE.Easy to identify: includes the ~25, ~75 kDa reference bands coupled with a green and a red dye.Ready-to-use: supplied in a loading buffer for direct loading on gels.Broad range: 10-245 kDa (Tris-glycine-SDS running buffer).The ladder is supplied in gel loading buffer and is ready to use. 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. 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 BLUeye Prestained Protein Ladder is a three-color protein standard with 12 prestained proteins covering a wide range molecular weights from 10 to 245 kilodalton (kDa).
