FF beads coated with antibodies recognizing specific carcinoma cell-surface antigens are added onto fixed samples of carcinoma cells, and a magnet is attached beneath them to enhance the antigen-antibody reaction
For whatever reason, normally harmless protein substances in certain foods may be mistaken by the body's immune system for dangerous substances against which it must mount a defense -- the antigen-antibody reaction
Immunodiagnostics is a class of diagnostics tests that utilizes antigen-antibody reaction
for the detection of diseases.
When standard adsorption studies are required, numerous technical procedures are employed nationwide, which include untreated RBCs without antigen-antibody reaction
potentiators, untreated RBCs with potentiators such as low ionic strength solutions (LISS) or polyethylene glycol (PEG), enzymatic treatment of RBCs without potentiators, and enzyme treated RBCs in conjunction with various potentiators.
The specificity of the antigen-antibody reaction
is astounding; it is possible to measure picomolar concentrations of proteins, peptides, and haptens in the presence of a 10 million-fold excess of closely related molecules, e.
