![]() ![]() The left panel demonstrates indirect detection while the right panel shows direct detection. Schematic representation of colorimetric western blot detection. Stains to visualize and quantify protein bands on gels and blots: Coomassie stains, highly sensitive fluorescent stains, silver stains, negative stains, and total protein blot stains. Chemiluminescent blotting Colorimetric western blotting Figure 1. Western blotting products include Stain-Free Western Blotting Workflow, protein transfer systems, blotting membranes, filter paper, premixed blotting buffers and reagents, and detection kits. Prestained and unstained molecular weight standards for protein electrophoresis applications including SDS-PAGE, western blotting, 2-D PAGE, and isoelectric focusing (IEF).įind solutions for all your antibody needs: an extensive inventory of primary and secondary antibodies, controls, and reagents plus custom products including monoclonal generation in just 8 weeks. Chemiluminescent detection is much more sensitive than colorimetric in the femtogram range compared with the picogram range of colorimetric detection. Protein Ladders and Standards (Markers).Choose SDS-PAGE and native PAGE gels, convert to TGX Precast Gels, or choose specialized gel chemistries. Trans-Blot Turbo Transfer Packs provide greater transfer efficiency in less time.įind the right Bio-Rad protein gel for your application. This eBook explores these solutions in detail and the advantages they offer researchers conducting western blotting in the lab. The increasing costs for film, reagents, and maintenance have driven researchers away from darkrooms to more sensitive and technologically advanced digital imaging systems. Northern or Western blot tests, and dot blot hybridization reactions with chemiluminescence detection. Rat brain homogenate (lanes 2 and 3) and biotinylated protein molecular weight markers. Western blot detection methods have traditionally used X-ray films to capture chemiluminescence. detection probe (e.g., antibody or DNA fragment). The Trans-Blot Turbo system is a rapid protein transfer apparatus that can transfer protein to membrane in as little as 3 minutes. With a variety of detection techniques for western blotting-chemiluminescence, fluorescence, or colorimetric, to choose from, you can select a technology to match your experimental requirements. The Amersham ImageQuant 800 GxP biomolecular imagers, developed by Cytiva, offer many benefits for chemiluminescence and fluorescence detection, including enhanced sensitivity, resolution, and data security.
