WebAn 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 ...
WebBiochemical tests are applied to the appropriate specimen and include gram staining followed by culturing the bacterial isolate in mannitol salt agar. Differentiation of the species is further characterized by enzyme tests including catalase (characteristically positive for all Staphylococcus species) and coagulase (specific for S. aureus ). WebA. Lowry Assay. The Lowry reaction for protein determination is an extension of the biuret procedure. The first step involves formation of a copper-protein complex in alkaline solution. This complex then reduces a phosphomolybdic-phosphotungstate reagent to yield an intense blue color. This assay is much more sensitive than the biuret method ...
