Sequence analysis of the variable region of a mouse gene encoding a monoclonal anti-idiotypic antibody that detects a restricted idiotype on anti-HIV-1 gp160.

We have sequenced the cDNAs encoding the variable (V) regions from the light and heavy chains of a monoclonal anti-idiotypic antibody (Ab), designated MC1, that, when used as an immunogen, activates regulatory idiotypes associated with anti-HIV-1 gp 160 responses. This anti-Id represents a non-antigen-mimicking subclass of Ab-2 referred to as non-internal image. The gene family selections and sequence homologies are presented.
