The ColorMixed Protein Marker 250 is a ready to use two-color protein standard with 11
pre-stained proteins covering a wide range of molecular weights from 10 to 250 kDa (10 to
230 kDa in Bis-Tris (MOPS) buffer and 9.8 to 230 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with a blue chromophore except for two reference bands (two red bands at 25 kDa and 70 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). This marker 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.
