Electrophoresis/Western Blotting

Why western blotting, a technique used in every day research, is still not as straightforward as it seems? Well, it’s mainly because of the antibodies. They may not work in all samples, a lot of standardization needs to be done and there are several other unknowns. Bio-Rad, the leader in western blotting, has addressed these concerns in its newest line of antibodies, the PrecisionAb™ Antibodies. See the challenges and the Bio-Rad solution.

Which antibody is the best to obtain a definitive and conclusive answer for my questions? How do I choose the best antibody for my purpose? These are standard questions that scientists ask time and time again. Here are a few tips to choose the most appropriate antibody for your specific application.

Immunoprecipitation (IP) is a commonly used protocol for concentrating and purifying proteins using specific antibodies and magnetic beads. Here is a simple IP protocol using Bio-Rad’s SureBeads Magnetic Beads.

What is stain-free technology? How does it work in electrophoresis and western blotting? How does it compare with existing staining techniques? What are its advantages and possible concerns? Here is a technical review of this rapidly growing technological advance.

For a long time X-ray film has been the standard for imaging western blots, but this method has its limitations. Find out how 3 researchers are using the digital tools offered by the new ChemiDoc Touch Imaging System to beat these limitations and improve their blot images.

Take a quick look at Bio-Rad’s brighter Precision Plus Protein™ Dual Color Standard with this article comparing this standard to other available protein markers. Plus, find out why the ability to visualize a protein standard after reprobing matters to one researcher!

Hand casting polyacrylamide gels is not an easy task. It is laborious, needs lot of pre-planning and is cumbersome. Bio-Rad’s new TGX and TGX Stain-Free FastCast gel solutions not only address all these issues, but provide added benefits, such as increased speed, stain-free visualization, and quality control. Learn more about these new handcasting kits.

Evaluating potential protein therapies for purity and/or identity represents a vital and highly regulated step in biological drug development. Bio-Rad’s new Biologics Analysis Workflow™ offers a high-throughput, sensitive, and reproducible solution that is cGMP-compliant.

Twenty years after the discovery of the link between BRCA gene mutations and breast cancer, researcher Ryan Jensen of the Yale Medical School is looking into the interactions between the DNA repair protein RAD51 and BRCA proteins using Bio-Rad’s V3 Western Workflow.

Removing host cell protein (HCP) contaminants represents an essential step in the production of biologics (therapeutic protein drugs), but has long been a time- and labor-intensive process. Here, we demonstrate a simpler, quicker, and more standardized workflow for evaluating anti-HCP antibodies using 2-D electrophoresis and western blotting.
