In the Fluorescence Polarization Immunoassay (FPIA) Technique, the Amount of Polarized

Multiple Choice

In the fluorescence polarization immunoassay (FPIA) technique, the amount of polarized fluorescent light detected when the fluorophore is excited with polarized light is higher for:

A) low-molecular-weight fluorescence-labeled ligands not bound to antibody
B) low-molecular-weight non-labeled ligands not bound to antibody
C) low-molecular-weight fluorescence-labeled ligands bound to antibody
D) low-molecular-weight non-labeled ligands bound to antibody
