2-D electrophoresis is a multistep technique that separates proteins first by a protein’s isoelectric point and then by its molecular weight. This powerful technique can separate thousands of proteins in a complex proteome and is useful for applications such as protein profiling and biomarker discovery. The drawback of the technique is that it requires multiple steps, each of which can be time-consuming and can contribute to problems with reproducibility.

Mini-PROTEAN® TGX Stain-Free™ and Criterion™ TGX Stain-Free™ precast gels, when combined with Bio-Rad’s ChemiDoc™ MP or Gel Doc™ EZ imagers, provide researchers with the fastest protein separation and visualization available using the standard Laemmli system.

The HTE sensor chip is designed for label-free biomolecular interaction analysis with polyhistidine-tagged proteins. It features a novel tris-NTA (3-NTA) surface for excellent performance of polyhistidine-tagged protein capture, providing high binding stability and regeneracy. It is an ideal choice for the applications of protein-small molecule and other protein interactions requiring high sensitivity.

This year the California Separation Science Society will present its annual Scientific Achievement Award to Professor Stellan Hjertén of Uppsala University. The award dinner will be held November 3, 2011 at the Waterfront Hotel in Jack London Square.

The ChemiDoc MP imaging system enables stain-free operation and lets you visualize proteins at every stage of your experiment. Its flexibility and sensitivity are complemented by a simple, intuitive operation that integrates seamlessly into your workflow.

Introducing Bio-Rad’s PROTEAN i12 IEF system. Each channel in the i12™ focusing tray is powered by its own power supply, enabling precise control over each IPG strip. This makes it possible to run different sample types, different gradients, and multiple protocols all at the same time.

Immun-Blot LF (low fluorescence) PVDF membranes are protein blotting membranes optimized for fluorescent and multiplex fluorescent applications. They offer high signal-to-background ratio, low autofluorescence, and superior protein retention to maximize blot detection sensitivity and enable downstream quantitation.

Watch how the Bio-Plex® suspension array system has contributed to research findings in Dr Francis Spinale and Dr Steven Kornblau’s laboratories that have the potential to impact screening and treatment of disease.

Harvard Medical School Postdoctoral student Sririam Kosuri explains how the Gel Doc EZ system has changed the way researchers image gels in the George Church lab at Harvard Medical School’s Wyss Institute.
