Enzyme-Linked Immunosorbent Assay (ELISA) is a useful, highly sensitive and powerful technique for the detection of proteins, chemicals, and drugs (antigens) in biological samples, including serum, blood and urine. The key to an ELISA is the interaction of a known antibody with the antigen of intere..
