Abstract
The present invention relates to immunological receptors and ligands, and more particularly to monoclonal receptors raised to
peptides whose amino acid residue sequences correspond to sequences of retroviral ligands. The receptors are used to assay
body samples from a host to indicate exposure of the host to a carcinogen.
