immunoassay techniques

**immunoassay techniques**

Immunoassay techniques are laboratory methods used to detect or quantify specific proteins, hormones, antibodies, or antigens in a sample by using the principles of antigen-antibody binding. These techniques are widely employed in medical diagnostics, research, and pharmaceutical development due to their high sensitivity and specificity. Common types of immunoassays include ELISA (enzyme-linked immunosorbent assay), radioimmunoassay (RIA), and chemiluminescent immunoassays. Understanding immunoassay techniques is essential for professionals in immunology, biochemistry, and clinical laboratories.
