Solutions Needed: 0.1M Sodium Bicarbonate (pH 9.4-9.6), Blocking Solution (1X PBS+10% The ELISA assay yields three different types of data output: Quantitative: ELISA data can be interpreted in comparison to a standard curve (a serial dilution of a known, purified antigen) in order to precisely calculate the concentrations of antigen in various samples. Authoritative and easily accessible, ELISA: Methods and Protocols seeks to provide both professionals and novices with the technical information necessary for the reader to successfully use the immunoassay as part of the discovery process. In a traditional (direct coating) ELISA, antigens are directly attached to the plate by passive adsorption, usually using a carbonate/bicarbonate buffer at pH >9.
