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

电泳概述
电泳是在溶剂中通过电场转移带电分子，任何带电的离子或者基团放置在电场中都将会迁移。除非在它们的等电点，大多数生物聚合物在任何pH值时都带有净电荷，它们将会以与电荷密度成比例的方式移动。分子在电场中的迁移取决于电场的强度、净电荷、分子的大小和形状、离子强度、粘度和分子移动介质的温度。作为一种分析工具，
