10-250kDa Wide Range Blue-Red-Green Three Color Protein Ladder, Prestained

11 band: 10, 15, 20, 25 (Green), 35, 40, 50, 70 (Red), 100, 150, 250 kDa: Bio Basic prestained protein ladder is designed for estimating the approximate size of separated proteins on SDS-PAGE gel. The ladders are a mixture of recombinant proteins ranging from 10 kD to 250 kD. Red or green bands at 70 kD and 25 kD provide easy references for molecular weight identification. The molecular weights of the prestained ladders are confirmed using the Tris-Glycine SDS-PAGE system with an accuracy of >95% by using unstained protein ladders. The protein ladders are highly stable with minimal band broadening during storage. Products are conveniently packaged and ready to use， with no heating, diluting or additional reducing agent required.
