Protein conjugates and their preparation.

摘要

Protein conjugate compounds useful in liposome immunoassays have the formula: <CHEM> wherein R is derived from an organic compound containing 1,2-dihydroxy groups which groups are subject to oxidative cleavage; X and X min are the side chain moieties connecting the R moiety to the carbon atoms resulting from oxidative cleavage of the 1,2-dihydroxy groups; P and P min are proteins or protein derivatives; and R min is H or ethyl; and R sec is derived from a steroid having at least one carbonyl group which forms the oximino moiety =N-O.
