ClearBand Prestained Protein Marker II is a protein standard containing 11 pre-stained proteins covering a wide molecular weight range from 8 to 270 kDa.
 
Proteins are covalently coupled with a blue chromophore except for three reference bands (at 8 kDa, 30 kDa and 90 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer). This protein marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes and for approximating the size of proteins. The protein marker is supplied in gel loading buffer and is ready to use.
