Practical Tips of ELISA Enzyme-linked Immunosorbent Assays (ELISAs) combine the specificity of antibodies with the sensitivity of simple enzyme assays, by using antibodies or antigens coupled to an easily-assayed enzyme. ELISAs can provide a useful measurement of antigen or antibody concentration. Being one of the most sensitive immunoassays, ELISA offers commercial value in laboratory research, diagnostic of disease biomarkers, and quality control in various industries. There are different types of ELISA according to the analyte detection method. Each of them have its own protocol but the basic principle is similar. An ELISA is a generally a five-step procedure: 1) Antigen coating; 2) Blocking all unbound sites to prevent non-specific absorption; 3) Add analyte and incubation; 4) Add labeled antibody and incubation; 5) Add reagents for colouration/ luminescence, thus give a positive result. We have already discussed the ELISA format and general protocol in ELISA Guide and ELISA Development Guide. Here we mainly discuss about some basic knowledge and practical tips during the operation process of ELISA.
