Bispecific antibodies directed against the rat aß-T cell receptor
and rat tumors of epithelial origin
Quadroma Clone Antibody Isotype Cat. No.
R73xCC52 Mouse IgG1 x Mouse IgG1 ARA17
Generation This bispecific antibody was generated by fusion of the R73-producing
hybridoma with the CC52-producing hybridoma (Beun et al., 1993).
Quadroma clones producing functional bispecific antibodies were selected
by testing the ability of the quadroma products to induce T cells to lyse the
appropriate tumor cells.
Reactivity
R73xCC52 consists for one half of an antibody that is directed against the rat
aß-T cell receptor and for the other half of an antibody directed against an
antigen present on tumor cells of epithelial origin. Specific information about
the reactivity of R73 and CC52 can be found elsewhere on this website.
Technical information
The bispecific antibodies induce lysis of appropriate tumor cells by rat T cells
(Beun et al., 1993) and are, therefore, extremely useful to test the lytic capability
of rat cytotoxic T cells.
