  • Title: An enzyme-linked immunosorbent assay to quantitate the elastin crosslink desmosine in tissue and urine samples.
    Author: Gunja-Smith Z.
    Journal: Anal Biochem; 1985 May 15; 147(1):258-64. PubMed ID: 4025822.
    Abstract:
    An enzyme-linked immunosorbent assay method has been developed for the determination of desmosine. The method is based on an inhibition immunoassay (under nonequilibrium conditions) and uses rabbit antisera directed against a desmosine-bovine serum albumin conjugate and microtiter plates coated with desmosine-gelatin conjugate. The assay quantitates desmosine in the range 2.5-50 pmol in tissue and urine samples. Important applications of this rapid and sensitive assay are in studying elastin metabolism and in screening for monoclonal antibodies against desmosine. Methods are described for obtaining a constant level of substitution of desmosine per molecule of bovine serum albumin and for preparing a desmosine-gelatin coating antigen. Five different antibody preparations directed against desmosine exhibit 15-20% cross-reactivity toward pyridinoline (3-hydroxypyridinium), a nonreducible collagen crosslinking compound also present in urine and many tissue samples.
