title: An improved solid-phase immunoassay for anti-GBM antibodies.
abstract: A solid-phase immunoassay has been developed for the detection of anti-glomerular basement membrane (GBM) antibodies in the circulation of patients with Goodpasture's syndrome and one form of rapidly progressive glomerulonephritis. The procedure involves the formation of a covalent linkage between the antigen and a solid support disc. Antibodies bound to the antigen are then detected on a fluorometer using fluorescein-labeled antisera to human immunoglobulins. The assay is easy to perform, fast, inexpensive and has been optimized with respect to sensitivity, range and reproducibility.
