Signaling assays define
An immunoassay (IA) is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay is often referred to as an "analyte" and is in many cases a protein, although it may be other kinds of molecules, of different sizes and typ… WebThat is the case for Abcam’s TNF alpha ELISA Kit ( ab208348 ). The protocol includes a table of ranges of plasma dilutions that are within the dynamic range of the assay. At the low end of the dynamic range, the ELISA could accurately detect the protein in dilutions equivalent to 1/16 (6.25/100, or 6.25 %). At the high end of the dynamic ...
