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. Stellar NIR/IR fluorescence detection offers comparable sensitivity to Simple Western chemiluminescence and higher sensitivity than competing traditional fluorescence western blotting approaches. The left panel demonstrates indirect detection while the right panel shows direct detection. Colorimetric Two of the most commonly used enzymes in colorimetric detection are alkaline phosphatase (AP) and horseradish peroxidase (HRP). Schematic representation of colorimetric western blot detection. This is the basis of colorimetric and chemiluminescent detections, respectively. Western blotting products include Stain-Free Western Blotting Workflow, protein transfer systems, blotting membranes, filter paper, premixed blotting buffers and reagents, and detection kits. Chemiluminescent blotting Colorimetric western blotting Figure 1. Choice of the HRP chemiluminescent substrate used should be based on abundance of your target protein of interest, abundance of sample containing the target protein, quality of the antibodies and the level of sensitivity and type of instrumentation available for detection.

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. Protein Ladders and Standards (Markers) With this leap in sensitivity, Stellar fluorescence detection rivals the widely recognized sensitivity of chemiluminescence detection and demolishes the fluorescence detection of the closest competing traditional Western blot imaging instrument, which requires at least 50 pg.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. To further confirm that BCFs are fibroblasts, this study performed VIM and CK18 expression detection using qPCR, western blot, and immunofluorescence stain. Just load your samples and reagents into the microplate and Jess separates your proteins by size, and precisely manages antibody additions, incubations, washes and even the detection steps. The Trans-Blot Turbo system is a rapid protein transfer apparatus that can transfer protein to membrane in as little as 3 minutes. Jess automates the protein separation and immunodetection of traditional Western blotting, eliminating many of the tedious, error-prone steps.
