In the most simple form of an ELISA, antigens from the sample to be tested are attached to a surface. The enzyme linked immunosorbent assay (ELISA) is a powerful method for detecting and quantifying a specific protein in a complex mixture. The enzyme-linked immunosorbent assay (ELISA) is an immunological assay commonly used to measure antibodies, antigens, proteins and glycoproteins in biological samples. Easier to perform and uncomplicated process as compared to other assays which require the presence of radioactive materials. An enzyme conjugated with an antibody reacts with colorless substrate to generate a colored product. ELISA has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries. The amount of antibody that binds the antigen is proportional to the amount of antigen present, which is determined by … read more... Brochure. Competitive ELISA – Microtiter well which is antigen-coated is filled with the antigen-antibody mixture. ELISA is based on the principle that specific antibodies bind to their target antigen i.e it is based on the principle of antigen-antibody interaction. ELISA can be used to detect some of these conditions: Following are some of the advantages of the ELISA technique: Results fetched from ELISA gives an accurate diagnosis of a particular disease since two antibodies are used. Detection systems are usually designed to produce a color change that can be quantified by a microtiter plate reader. Enzyme-linked immunosorbent assay (ELISA) is a method allowing the quantification of a desired marker in a biological sample.
