An assay is a procedure where a property or concentration of an analyte is measured. Numerous types of assays exist, such as an antigen capture assay, bioassay, competitive protein binding assay, crude oil assay, four-point assay, immunoassay, microbiological assay, stem cell assay, and many others, including concentration assays. Assays are regularly utilized in molecular biology scientific... Read enhanced Wikipedia article
