Application

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 sulfydryl 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 2-atom linker.

Caution

The iodoacetyl group is light sensitive.

Two methods for the preactivation of proteins and conjugation of peptides to proteins under mild conditions are presented. Preactivation of proteins with divinylsulfone (DVS) permits peptide conjugation through either amino, hydroxyl or sulphydryl groups depending on the coupling pH used

Anti-tumor immunity is limited by a number of factors including the lack of fully activated T-cells, insufficient antigenic stimulation and the immune-suppressive tumor microenvironment. We addressed these hurdles by developing a novel class of immunoconjugates, Antibody-Targeted Pathogen-derived Peptides (ATPPs), which

A novel procedure for the synthesis of well-defined protein-protein conjugates is described using ovalbumin (OA) and IgG as test proteins. This procedure involves the highly selective and rapid reaction of alkyl halide and sulfhydryl groups, which have been grafted, respectively
