Fig. 1From: Higher resolution protein band visualisation via improvement of colloidal CBB-G staining by gel fixationThe chemical structures of CBBR-250 and CBBG-250. The differences in the two dyes can be attributed to the addition of two methyl groups in CBB G-250, as indicated by the arrows in the diagram. Chemical structures were drawn using PubChem Sketcher [7]Back to article page
