SPDP 是一种短链交联剂，用于通过 NHS 酯和吡啶基二硫醇反应基团与半胱氨酸巯基形成可切割（可还原）的二硫键，实现胺与巯基的共轭。它是一种可降解的 ADC 连接剂，可用于合成抗体偶联药物。

SPDP is a short-chain crosslinker, which is used for amine-to-sulfhydryl conjugation via NHS-ester and pyridyldithiol reactive groups that form cleavable (reducible) disulfide bonds with cysteine sulfhydryls. SPDP could activate equal amounts of anti-CD11c and anti-CTLA-4 Abs (in borate buffered saline; pH 8.5).
