The Novex® Sharp Protein Standards provide corresponding bands in pre-stained or unstained format for various protein gel electrophoresis applications. They are suitable for use with Tris-glycine, Tricine, and NuPAGE® Novex® Gels, and offer:
• The sharpest bands - clearer estimation of MW compared to wide bands
• The broadest MW range - estimation over a larger range (3.5 kDa to 260 kDa)
• Ladder-like separation of bands - evenly spaced separation across the readable range for easy comparison at all molecular weights
• Ready-to-use format - no mixing or reducing required
The Novex® Sharp Pre-stained Protein Standard contains 12 proteins that resolve into sharp, tight bands in the range of 3.5-260 kDa (Figure 1). Each band is stained in a distinct color for easy band identification. The Novex® Sharp Pre-stained Protein Standard allows you to monitor molecular weight separation during electrophoresis, estimate molecular weights of proteins of interest, and evaluate western 查看更多transfer efficiency.
The Novex® Sharp Unstained Protein Standard contains 12 proteins that resolve into sharp, tight bands in the range of 3.5-260 kDa (Figure 2), corresponding to those in the Novex® Sharp Pre-stained Protein Standard. The Novex® Sharp Unstained Protein Standard provides accurate molecular weight estimation for gel electrophoresis.
