摘要: Type IV collagenase is a metalloproteinase associated with metastatic tumor cells. It specifically cleaves the triple helical basement membrane (type IV) collagen molecule at single site. Monoclonal antibodies which block activity of human type were developed and used to purify this antigen. The purified was partially sequenced following cyanogen bromide trypsin cleavage. amino acid sequence fragments revealed region homologous interstitial stromelysin. However, several sequences in identified are distinct from latter. Polyclonal raised against synthetic peptide derived such sequence. Following affinity purification, recognized denatured Western immunoblotting. These data indicate that member general family metalloproteinases.
