MCQ on ELISA (Enzyme Linked Immuno Sorbent Assay)




Enzyme-Linked Immunosorbent Assay (ELISA) is a biochemical test used to detect and quantify specific proteins, antibodies, or antigens in biological samples. It involves using antibodies and enzymes to create a color change that indicates the presence and concentration of the target molecule, making it valuable in various research and diagnostic applications. This an MCQ on ELISA Principles and Applications in Biological Research
