Abstract
Isolated complexes (which include basement membrane components), antibodies to such complexes or polypeptide constituents thereof, and methods for detecting such complexes or constituents are disclosed. Detection of such complexes in a biological sample by immunological and non-immunological methods allows the diagnosis of a variety of diseases, including cancers, collagen degenerative diseases, and hepatitis. Suitable biological samples include urine, cervical secretions, bronchial aspirates, sputum, saliva, feces, serum, synovial fluid, and cerebrospinal fluid.
