NuPAGEGels
NuPAGE GelsA gel electrophoresis system used for SDS-PAGE protein analysis. The gels are made up of Bis-Tris-HCl (pH 6.4) polyacrylamide and are intended for denaturing conditions only.NuPAGE Electrophoresis Protocols1) Remove gel from pouch and rinse gel with D.I. water holding the gel by the edges of the cassette. (Gels should be stored at 4º C)2) Mark the bottom of the lanes with a permanent marker.3) Peel off tap......阅读全文
