NuPAGE® LDS Sample Buffer (4X) (10 ml) is used to prepare protein samples for denaturing gel electrophoresis with the NuPAGE® gels. Optimal protein sample preparation for polyacrylamide gel electrophoresis (PAGE) requires denaturing and reducing the protein disulfide bonds. NuPAGE® LDS Sample Buffer contains lithium dodecyl sulfate at a pH of 8.4, which allows for maximal activity of the reducing agent. For native gel electrophoresis, use Novex® Tris-Glycine Native Sample Buffer (2X) . Note: NuPAGE® LDS Sample Buffer should be brought to room temperature (25°C) prior to use. NuPAGE® LDS Sample...

Ambion® Nuclease-free Water (not DEPC-treated) has been deionized, filtered into the final bottle, and autoclaved. It is ready to use and requires no preparation, mixing, or autoclaving. Because it is not DEPC treated, it is recommended for applications for which residual DEPC might prove detrimental (e.g. oocyte microinjection). This nuclease-free water is rigorously tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity.

Novex® Tris-Glycine polyacrylamide gel chemistry is based on the Laemmli system (1) with minor modifications for maximum performance in the pre-cast format. These gels do not contain SDS and can therefore be used to accurately separate both native and denatured proteins. Novex® Tris-Glycine Gels provide reproducible separation of a wide range of proteins into well-resolved bands. Formulation: Novex® Tris-Glycine Gels are made with high-purity, strictly quality-controlled reagents: Tris base, HCl, acrylamide, bisacrylamide, TEMED, APS, and highly purified water. They do not contain SDS. Recomme...
