PAGE-MASTER Protein Standard Plus is a special-designed protein standard by Genscript .The standard consists of nine proteins with molecular weight of 10kDa, 15KD, 20kDa, 30kDa, 40kDa, 50KDa 60kDa, 80kDa and 120kDa. The proteins of 15 KDa and 50KDa are pre-stained proteins coupled with blue dye for easy visualization. All the bands were highly purified, thus gives excellent performance in SDS-PAGE gels.
