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.
