- DNA replication
- Antigen-antibody interaction
- Pathogen–antigen interaction
- Antigen–protein interaction
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
ELISA (Enzyme-Linked Immunosorbent Assay) detects specific antigens or antibodies using the principle of antigen-antibody interaction.
The binding is detected through an enzyme-linked reaction, often resulting in a color change.
