Tri-Color Prestained Protein

Tri-Color Prestained Protein Markers are a mixture of recombinant proteins ranging from 10 kD to 250 kD. Red and green bands at 25 kD and 70 kD and provide easy references for molecular weight identification. The molecular weights of the prestained markers are confirmed in Tris-Glycine SDS-PAGE system with an accuracy of >95% by using unstained protein ladders. The protein markers are highly stable with minimal band broadening during storage. Products are conveniently packaged and ready to use, with no heating, dilution or additional reducing agent required. Formulation : 62.5 mM Tris-HCl (pH 7.5 at 25°C), 1 mM EDTA, 2% (w/v) SDS, 10 mM DTT and 30% (v/v) glycerol. Storage : 4 °C for up to 1 year while -20°C and -80°C for up to 3 and 10 years, respectively. Avoid repeated freezing and thawing.
