Monitor progress of protein electrophoresis and assess transfer efficiency and molecular weight of blotted proteins without staining. High intensity, prestained multicoloured bands allow distinction of closely related proteins.

• Full-Range Rainbow Markers (Mr 12,000 to 225,000) use ten separate proteins with six different colours
• High-Range Rainbow Markers (Mr 12,000 to 225,000) use eight separate proteins with six different colours
• Low-Range Rainbow Markers (Mr 3,500 to 38,000) use seven separate proteins with five different colours
• For use on SDS-PAGE
