What Does CELISA Stand For?

CELISA stands for Competitive Enzyme Linked Immunoabsorbent Assay

CELISA, or Competitive Enzyme Linked Immunoabsorbent Assay, is a diagnostic technique used to quantify specific antigens or antibodies in a sample. This method utilizes a competitive binding mechanism where a labeled antigen competes with the sample's antigen for binding sites on an antibody coated to a solid surface. The intensity of the resulting signal is inversely proportional to the concentration of the target analyte, allowing for precise measurement and analysis. CELISA is widely employed in various fields, including clinical diagnostics and research, due to its sensitivity and specificity.
