Protein Ladders

Protein ladder, also known as protein marker, is a mixture of highly purified protein pre-stained with a suitable dye- blue, orange or green to serve as a Molecular Weight Marker for techniques like protein 2-D electrophoresis, SDS-PAGE and Western blotting to estimate protein size. The range of protein size offered in a mixture varies, from 10 to 180 kDa or 3.5 to 245 kDa usually forming 8 or 10 bands coming from 8 or 10 different molecular weight proteins. The ladder is thermosensitive and needs to be stored at a temperature of -20C to avoid any sort of degradation. Biomall offers a vast range of Protein ladders to select the best suitable.
