The NativeMark™ Unstained Protein Standard is a ready-to-use protein standard designed for molecular weight estimation of proteins using native gel electrophoresis. Features of this marker:
• Versatile—recommended for use with Novex® NativePAGE™ Bis-Tris, gradient Tris-Glycine, or NuPAGE® Novex® Tris-Acetate gels • Comprehensive—contains markers with a wide range of high molecular weights, providing 8 protein bands in the range of 20–1,200 kDa • Convenient—no need to add sample buffer, just load and run • Compatible—can be visualized using Coomassie®, silver, or fluorescent stains after electrophoresis, or with Ponceau S, Coomassie®, or other membrane stains after Western transfer
Electrophoresis under native (nondenaturing) conditions maintains the native protein conformation, cohesion of subunits, and biological activity. During native electrophoresis, proteins are separated based on their charge to mass ratios.
