Protein Size Marker

AccuLadder™ 3-color Prestained Protein size marker (Broad) allows to estimate the sizes of proteins during protein electrophoresis. This product is composed of 12 different types of proteins (11 - 245 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), allowing each band to be distinguished with ease. AccuLadder™ 3-color Prestained protein size marker (Broad) is designed for monitoring protein isolation when observing Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and estimating the sizes of proteins. The ladder is supplied in a gel loading buffer, making it ready to be used.
