Multiple steps standard assay
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… WebThe assay can detect 0.005 mg/ml, so we'll dilute each fraction 100-fold, making 0.5 mg/ml in the undiluted fraction the minimum we can reliably detect. This requires that we consume only a tiny portion of each fraction. Set up a standard curve of protein dilutions in your plate. Plan a plate layout with two wells per unknown fraction.
