MCQ on RIA (Radioimmunoassay)

Radioimmunoassay (RIA) is a sensitive laboratory technique that uses radioactive isotopes to measure the concentration of specific substances, such as hormones or antigens, in biological samples. It involves competition between labeled and unlabeled molecules for binding to a limited number of specific antibodies. This is an MCQ on RIA (Radioimmunoassay)- Principles and Applications.
