Clinical and Procedure
Clinical Utility

This is a quantitative EIA assay for the human cytokine Transforming Growth Factor beta 1 ( TGF ß-1). TGF β-1 plays a role in tissue regulation and is used as an aid to determine underlying causes of unusual or inflammatory disorders. TGF β-1 is a pleotropic cytokine that possesses both inflammatory and immune-suppressive characteristics. It is a secreted protein that performs many cellular functions, including control of cell growth, proliferation, differentiation and apoptosis.


Multiplex array format with Meso Scale Discovery (MSD®) Sector Imager 2400. MSD Cytokine assays measure from one to ten cytokines in a 96 well MULTI-SPOT plate. The assay employs a sandwich immunoassay format. MSD technology uses electrochemiluminescence detection; a CCD camera allows for the quantification of light emitted from each spot in each well. MSD software generates a standard curve to determine sample cytokine concentrations. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.


Specific for TGF ß-1 and does not cross-react with TGF ß-2 and TGF ß-3.
