摘要: A cell matrix receptor specific for laminin expressed on the surface of carcinoma and epithelial cells is provided. The binding of these cells to extracellular matrix is mediated by the laminin molecule, which has binding domains for type IV collagen of the matrix and the cell surface receptor. Fragments of the laminin molecule lacking the type IV collagen binding domain and antibodies to the receptor are useful in conjunction with the cell receptor as ligands in binding assays for cancer diagnosis and in cancer management.
