The innate immune system is the body’s crucial first defense against viral infections and it is dependent upon a group of pattern recognition receptors. cGMP-AMP Synthase (cGAS) responds to the presence of DNA in the cytosol by producing 2’,3’cGAMP. Cyclic GAMP in turn binds to STING leading to TBK1-mediated IRF3 activation and the production of type 1 IFN.

Understanding the STING cell signalling pathway and the role cGAMP plays in a number of important areas, such as infection, cancer, inflammation & senescence, relies on cGAMP measurement. Good news – Arbor Assays have just released a new cGAMP EIA kit, read on to learn more!

Dr Yong Zhang, Ph.D. is a senior scientist and R&D Manager for antibody generation and assay development at Rockland Immunochemicals, Inc. who are recognised and renowned for their high quality primary antibodies, secondary antibodies and many other reagents for Life Sciences.

Dr Yong Zhang’s special focus is on collagen related products, and I’m sure you’ll find his expert tips and tricks that he kindly shares in this post very useful if you’re working with collagen immunoassays. Read on to the end, where you’ll find a selection of high quality, reliable collagen related reagents that may be very useful for your projects.

When scientists at ArborAssays invented the Direct Cyclic Nucleotide EIA immunoassay more than 20 years ago, they knew the kits would be popular. The direct nature of the format for the assays allows cAMP & cGMP in cells to be measured in one step. They went on to refine the assay, developing both colorimetric and chemiluminescent versions for cAMP and cGMP. But what makes them so popular?

As is well known, the actin cytoskeleton is a highly dynamic structure, involved in a large number of cellular processes, including muscle contraction, lamellopodial extrusion, cell locomotion, cytokinesis, intracellular transport and many more. Under the tight regulation of more than 50 actin binding proteins (ABPs) and in response to a wide variety of internal and external stimuli, the morphology of the actin cytoskeleton changes rapidly.

For more than 20 years now, Cytoskeleton Inc. has provided a large selection of robust and user friendly solutions (pure and active actin proteins/Biochemical assays and actin staining probes..) which have helped many researchers to solve fundamental questions in cell signalling, cytoskeleton and actin research fields.
