Protein Markers

Protein markers, often referred to as protein ladders or protein standards, consist of a mixture of purified native or recombinant proteins of defined molecular weight. They are used to easily monitor the progress of protein separation in a polyacrylamide gel, to monitor the efficiency of transfer during Western blotting, and to estimate the molecular weight of the investigated proteins. In this category you will find a first-class selection of "ready-to-load" protein markers covering a wide range of molecular weights. You can also learn more about our assortment of protein as well as DNA markers in our blog.
