Featured Western Blot Products

Find out how GoldBio's vast protein analysis product collection can help you detect your protein of interest through Western Blotting. You can use our Coomassie stains to visualize your protein band on SDS-PAGE and complete the blocking step using GoldBio's BSA. In addition, choose to detect your proteins on nitrocellulose or PVDF with our Ponceau S solution. Explore our antibody labeling kits, which are ideal for labeling your primary anitbodies with AP, HRP, FITC or one of our superior water-soluble CF™ dyes.

ProGlow™ Western Blot Protein Ladders are designed for Western blots. ProGlow™ ladders can be used to monitor electrophoresis progress and to visualize protein standard bands directly on X-ray film or digital analytical equipment. ProGlow™ ladders consist of eight recombinant proteins in the range of 12-90 kDa. The 70 kDa protein is a prestained marker used for monitor of the electrophoresis process and evaluation of Western transfer efficiency. The other seven markers can bind to human, mouse, rat, goat, sheep and rabbit IgG with their IgG binding site, allowing direct visualization of markers on the X-ray film after ECL development.
