GRS Protein Marker MultiColour PLUS

Ready-to-use three-colour protein standard suitable for monitoring protein separation during SDS-PAGE, size determination of proteins, and verification of transfer efficiency of Western Blotting onto membrane (compatible with PVDF, nylon and nitrocellulose). This marker is composed of 10 pre-stained proteins ranging from 6,5kDa to 270kDa. For easy identification of each band, it includes three reference bands of different colours that co-migrate with proteins of 30kDa (red), 52kDa (green) and 270kDa (red), respectively, when separated by 4-20% gradient SDS-PAGE using TGS Buffer.

SKU N/A Category


Ready-to-use pre-stained protein marker suitable for monitoring protein separation during SDS-PAGE, verification of Western Transfer Efficiency onto membranes and for estimation of the molecular weight of proteins and/or polypeptides in the range of 10-250kDa. The GRS Protein Marker Multicolour is composed of 12 bands: 10 blue bands and 2 reference bands with different colours for easy identification (one red band (~25kDa) and one green band (~75kDa)).
