Electrophoresis/Western Blotting

2-D electrophoresis followed by immunodetection of protein spots using western blotting is adopted commonly in proteomics studies. Here we present step-by-step instructions for obtaining accurate overlaps between the gel and the blot using the PDQuest 2-D gel analysis software.

Bio-Rad’s 2-D electrophoresis workflow offers better results in a shorter time. Take a detailed look at this workflow by downloading the updated edition of our How-To Guide.

Bio-Rad’s innovative Gel Doc EZ imaging system features something unique that no other imaging system has – brains.

When Dr. Fred Bauzon started his research, he worked with bioinformatics specialists to functionalize suitable gene candidates based on their expression levels with HMGCR transcript levels. All his experiments demonstrated a reduction in low-density lipoprotein receptor protein (LDLR) and candidate gene protein levels after the candidate gene was silenced. Here Bauzon discusses how TGX Stain-free precast gels have aided his research toward future drug targets for the therapeutic control of LDL uptake.

Bio-Rad’s new Clarity Western ECL substrate provides high sensitivity, long signal duration, and low background even at long exposures.

Bio-Rad’s latest semi-dry transfer system, the Trans-Blot® Turbo™, has changed the way researchers think about western blot transfers.

Learning to use analysis software can be time-consuming and following a manual can be challenging.

Mini-PROTEAN® TGX Stain-Free™ precast gels are now available in gradient format. This unique gel formation allows for fast gel electrophoresis and blotting, and does not require staining and destaining for imaging.

The updated Image Lab image acquisition and analysis software provides improved tools for total protein normalization using the stain-free technology.

Detecting dilute protein samples using standard protein gel stains can be problematic. One method of enabling increased sample capacity on gels is to increase the well size. The newly introduced 4x Laemmli sample buffer improves sample loading capacity, improving the detection of low-abundance proteins.
