Which procedure would be used for quantifying molecules in various body fluids and tissue extracts from unknown samples?
A) Immunocytochemistry
B) In situ hybridization
C) Radioimmunoassay
D) Autoradiography

Question

Quizplus · Accepted Answer

Radioimmunoassay is a technique commonly used for quantifying molecules in various body fluids and tissue extracts from unknown samples. It involves using a radioactively-labeled antigen to compete with the unlabeled antigen in the sample for binding to a limited amount of antibody. By measuring the amount of radioactivity bound to the antibody, the concentration of the molecule in the sample can be determined. Immunocytochemistry, in situ hybridization, and autoradiography are not typically used for quantifying molecules in unknown samples.
