Novel V3 Western Workflow™ Revolutionizes Protein Research

Although the Western blot is a core lab procedure, surprisingly little has changed in traditional bench work practice since its inception in 1979. The V3 Western Workflow delivers a streamlined solution to the conventional western blotting workflow as explored here by one protein researcher specializing in chronic obstructive pulmonary disease (COPD).

Application of Hexapeptide Libraries for Enhanced Protein Detection in Human Cellular Lysates

Hexapeptide libraries, such as Bio-Rad’s ProteoMiner™ protein enrichment technology, can significantly increase sensitivity of shotgun proteomics analyses of diverse complex samples. Underlying this increased sensitivity is the partial removal of high-abundance proteins leading to an increased representation of low-abundance proteins — a phenomenon described as dynamic range compression. Currently, hexapeptide libraries have been mostly used to increase proteomic detection in fluid samples (eg: saliva, plasma, etc.), but not in cellular lysates.

Transitioning from Chemiluminescent to Multiplex Fluorescent Blotting: Things to Consider

Today many researchers are considering changing their western blot detection method from chemiluminescence to multiplex fluorescence. There are several drivers behind this trend. Most significantly, fluorescent detection allows users to multiplex their western blots, enabling simultaneous detection of several target proteins at once, reducing or eliminating the need to strip and re-probe. Other benefits of fluorescence include better dynamic range, more quantitative results, and better signal stability over time.
