Prestained Protein Ladders

Prestained protein ladders are available from several suppliers for protein gel electrophoresis and related applications. These ready-to-load protein standards come premixed with loading dye and allow users to distinguish protein molecular weights with dye-stained proteins. Each sizing band consists of a purified protein of a known molecular weight. Protein ladders can provide useful information on protein size, relative abundance, and sample purity. Visit the supplier page for more details, including the applicable range of protein sizes and included colors.
