An enzyme-linked immunoassay for the collagen cross-link pyridinoline.
An inhibition immunoassay method for the determination of pyridinoline was developed with the use of microtitre plates coated with a pyridinoline--gelatin conjugate and rabbit antisera directed against pyridinoline linked to bovine serum albumin. The sensitivity of the assay is about 2pmol of pyridinoline, and the presence of related pyridinium and lysine-derived compounds does not significantly interfere with the procedure. Its application to tissue and human urine samples is described.
