ABSTRACT OF THE DISCLOSURE A novel polyfunctional disulfide compound of the formula Image where R is 2-benzothiazolyl or 2-pyridyl-N-oxide, and X is a spacer group having an alkylene group directly bound to the S-S group, is disclosed. It is useful as a cross- linking reagent having S-S exchange reactivity and which exhibits two different stepwise reactivities for compounds having a thiol group, and therefore is useful as a cross- linking agent for bound complexes of an enzyme and hapten, antigen or antibody, and as an immobilizing agent for an enzyme or hapten and a carrier.
