Module 12: Immunological Testing Methods Obj. 5 Flashcards
1
Q
4 main groups of labels used in immunoassays
A
Radioactive
Enzyme
Fluorescent
Chemiluminescent
2
Q
Radioimmunoassay (RIA)
A
utilize atoms with unstable nuclei that emit radiation that can be detected using a counter
3
Q
Enzyme immunoassay (EIA)
A
utilize non-isotopic labels
Enzyme labeled Ab or Ag may be used
4
Q
Fluorescent Immunoassay (FIA)
A
molecules which will absorb the energy of a photon of one wavelength and emit a photon of a slightly longer (lower energy) wavelength
5
Q
Chemiluminescence immunoassay (CIA)
A
substrates are modules which emit a photon of light as a result of a chemical reaction
ex. Luminol
