Enzyme-Linked Immunosorbent Assay (ELISA) is a commonly performed laboratory test on a blood or urine sample utilizing the antibody specificity as well as the sensitivity of enzyme assays. ELISA Kits helps in the detection and quantification of biomolecules such as antibodies, peptides, proteins, and hormones. There are three ways to perform ELISA: Double Antibody Sandwich ELISA, Indirect ELISA, and Competitive ELISA. These bring about a wide variety of applications in different areas including forensic, food, and clinical research.
