We have shown that lymphocyte-myeloma cell hybridization can be used to produce large amounts of extremely high-titer specific antibodies against type I collagen, a macromolecule normally of low immunogenicity. In a passive hemagglutination assay the antibody had a high titer against chicken type I collagen but showed no activity against chicken type II or rat type I collagen. By using a two-step fluorescence histochemical procedure on sections of embryonic chicken tibia, strong fluorescence was observed in the perichondrium and surrounding connective tissue (known to contain type I collagen) but not over the cartilage (characterized by type II collagen). When used in conjunction with Staphylococcus aureus as a solid phase immunoadsorbant, the antibody was shown to bind to labeled collagen synthesized in vitro by embryonic chicken calvaria.
