MCE 3-Color Prestained Protein Marker (10-180 kDa) consists of 10 prestained recombinant proteins with an apparent molecular weight range of 10–180 kDa. This marker enables real-time monitoring of protein migration during SDS-PAGE and facilitates evaluation of protein transfer efficiency. The 250 μL is defined as the base specification. All larger sizes correspond to incremental volumes of this base.
