Application

A heterobifunctional cross-linking reagent containing an extended spacer 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 thioether linkage buffered at pH 7.5 (7.0-8.0). Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates. Provides a 9-atom linker.

Caution

The iodoacetyl group is light sensitive.
