| Description | SPDP NHS ester is a heterobiofunctional crosslinker which can react with amine and sulfhydryl groups. SPDP NHS esters are membrane permeable therefore allowing them to funtion inside of cells. | | Chemical Properties | White Solid | | Uses | Important crosslinking reagent for the preparation of protein-protein and peptide-protein conjugates linked by disulfide bonds. | | Uses | A heterobifunctional cross-linker | | Uses | 3-(2-Pyridyldithio)propionic acid N-hydroxysuccinimide ester (SPDP) is useful for the preparation of enzyme immunoconjugates and hapten carrier molecule conjugates.
It has been used for antibody conjugation and as a protein cross-linker. | | General Description | 3-(2-Pyridyldithio)propionic acid N-hydroxysuccinimide ester (SPDP) is a heterobifunctional cross-linking reagent with amine and sulfhydryl reactivity. It is 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. It incorporates four atom linker. |
