产品名称:SPDP 英文名称:N-Succinimidyl 3-(2-Pyridyldithio)propionate 中文名称:3-(2-吡啶基二硫基)丙酸N-羟基琥珀酰亚胺酯 CAS #: 68181-17-9 简介:SPDP crosslinker is a cleavable, water insoluble, amino and thiol (sulfhydryl) reactive heterobi-functional protein crosslinker. The SPDP crosslinking reagent's reactive moites consist of an N-hydroxysuccinimide (NHS) ester that reacts with primary amines. On the other end of SPDP, the pyridinyldisulfide reacts with sulhydryls to yield a reversible disulfide bond. Application 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.
