The antibodies were produced by injecting purified type X collagen into female SJL/J mice and then fusing their spleen cells with Sp2/0 myeloma cells. Hybridoma culture supernatants were screened for antibodies to type X collagen by enzyme-linked immunosorbent assay and Western blots. Positive supernatants did not cross-react with other collagen types (I, II, IX, XI) or with fibronectin. Three monoclonal antibodies were chosen for further characterization. Two of them (1A6 and 6F6) recognize a pepsin-sensitive domain of type X collagen. Rotary shadowing showed that 1A6 and 6F6 both recognize the same end of type X, probably the aminoterminal non-triple helical domain. Amino acid sequencing of the intact protein and of the epitope-containing peptide confirmed that the antibody recognition sites for 1A6 and 6F6 are within the amino-terminal domain. Monoclonal antibody 2B3 reacts with the pepsinized (45 kDa) and weakly with the nonpepsinized (59 kDa) forms of type X collagen. The monoclonal antibodies were used for immunolocalization of type X in hypertrophic chondrocytes and reacted only with tissue samples from areas undergoing endochondral ossification, e.g. growth plate and fracture callus. Antibody 6F6, when coupled to Sepharose, selectively binds to type X collagen from cell and organ cultures. In a pulse-chase experiment, no processing of the 59-kDa form of type X could be detected. Two components with molecular masses of approximately 70 and 85 kDa, arising from a disulfide-bonded aggregate, were synthesized by both the permanent and calcifying cartilage organ cultures but did not react with the antibody, suggesting that these proteins are not related to type X. In summary, the pulse-chase results and the immune precipitation with monoclonal antibody 6F6 did not detect biosynthetic precursors larger than 59 kDa or proteolytically processed forms of type X."xsd:string
