  • Blue


The Blue Marker Antibody (6F4-F6) is a unique antibody that specifically detects the blue prestained molecular weight markers from different vendors. With the Blue Marker Antibody there is no longer a need to manually mark your protein marker bands and guess how accurately the marker bands were charted. The Blue Marker Antibody visualizes the markers together on the same western blot as your protein of interest. This antibody has outstanding specificity, it does not interfere with the detection by other antibodies and does not cross-react with whole cell proteins of different species.
