Anti-idiotypic antibodies made against the antigen-binding receptors of T lymphocytes for a given antigen (Ag-B locus antigens in rats) can be shown to react with IgG same reactivity. Using such anti-idiotypic antibodies, normal Lewis B and type visualized by use anti-(Lewis-anti-DA) antibodies. Visualization was possible direct fluorescent antibody tests or autoradiography. first technique naked eye observations 6.2% expressed idiotypic markers signifying anti-DA reactivity, whereas anti-DA-reactive as measured this approach order 1.1%. Autoradiography purified gave similar figures. When comparing intensity fluorescence at single cell level using quantitative cytofluorometry reactive degree obtained anti-Ig lymphocytes.
