Our prestained protein ladders and standards allow for easy identification and monitoring of your proteins during electrophoresis. These prestained ladders are available in low, broad, and high molecular weight ranges, and provide sharp bands for ease of visualization. Additionally, our multi-color ladders provide unambiguous reference points for identifying bands corresponding to their molecular weights, even if some bands are run off the bottom of the gel.

Each protein ladder or standard has its own advantages. The table and information below offers help in select the appropriate protein ladder for your application.
