What is full name of "ELISA"?

Concept-

• ELISA means Enzyme-Linked Immuno-sorbent Assay.
• ELISA techniques serve the purpose of early diagnosis.
• ELISA is based on the principle of antigen-antibody interaction.
• Infection by a pathogen can be detected by the presence of antigens (proteins, glycoproteins, etc.) or by detecting the antibodies synthesized against the pathogen.

Explanation-

• ELISA uses an enzyme to detect the binding of antigens and antibodies.
• The enzyme converts a colorless substrate to a colored product, indicating the presence of Ag: Ab binding.
• An ELISA can be used to detect either the presence of Antigens or antibodies in a sample depending on how the test is designed.
• ELISA was developed in 1970 and became rapidly accepted.
• ELISA is used for the diagnosis of AIDS.
• The working principle of ELISA is antigen-antibody interaction.
