ProteinRuler^® IV is composed of six unstained recombinant proteins (40 kDa, 60 kDa, 80 kDa, 100 kDa, 150 kDa, 200 kDa ) and one blue prestained recombinant protein (30 kDa). The prestained band allows monitoring electrophoresis. The 100 kDa band has doubled intensity to serve as a reference band.

• MW range from 30 to 200 kDa.
• Ready-to-use format, direct load on gels without heating.

Storage
at -20℃ for two years.

Shipping
Dry ice (-70℃).
