Abstract

Abstract Divalent hapten derivatives wherein two hapten moieties are connected by means of a bifunctional spacer wherein the derivative has the formula A--X--A where A is a bonded hapten moiety and X is a bifunctional spacer having the formula (B).sub.m --Y--(CH.sub.2).sub.n --Z--(CH.sub.2).sub.n --Y--(B).sub.m where m is independently 0 or 1, B is (CH 2 ) n' , wherein n' is an integer from 1 to 4, or CO(CH 2 ) n" , wherein n" is an integer from 2 to 4; Y is independently --CONH--, NHCO--, OOC--, --COO--, --O--, --S--, or --NR--, wherein R is hydrogen or alkyl; n is an integer from 1 to 10; and Z is an organic moiety containing at least one hydrophilic atom are disclosed.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 159 words
A divalent hapten derivative comprising two hapten moieties connected by means of a bifunctional spacer having the formula A-X-A where A is a bonded hapten moiety and X is a bifunctinal spacer having the formula (B).sub.m --Y--(CH.sub.2).sub.n --Z--(CH.sub.2).sub.n --Y--(B).sub.m where m is independently 0 or 1, B is (CH 2 ) n ', wherein n' is an integer from 1 to 4, or CO(CH 2 ) n " is an integer from 2 to 4; Y is independently --CONH--, --NHCO--, --OOC--, --COO-- --O--, --S--, or --NR--, wherein R is hydrogen or alkyl; n is an integer from 1 to 10; and Z is selected from the group consisting of -alkylene-O-alkylene-, alkylene-NH-alkylene, ##STR12## where the term alkyl means a straight or branched chain saturated hydrocarbon group having 1 to 6 carbon atoms and the term alkylene refers to a bivalent radical of the branched or unbranched alkyl group it is derived from having valence bonds from two terminal carbons thereof.
