Description
A heterobifunctional cross-linking reagent with amine and sulfhydryl reactivity. Typically, coupled initially to molecules containing primary amines by amide bonds buffered at pH 7.5 (6.5-8.5). Second coupling specific for molecules containing free sulfhydryl by thiol-disulfide exchange buffered at pH 8.0 (7.5-8.5). Alternately, this reagent may be used as a protected thiolating reagent following initial coupling and reduction of linker. Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates. Incorporates 4 atom linker.Related product price
