n-Succinimidyl 3-(2-pyridyldithio)propionate, also known as SPDP, is a heterobifunctional crosslinker used in bioconjugation. It contains a reactive N-hydroxysuccinimide (NHS) ester that reacts with primary amines on proteins, and a 2-pyridyldithio group that can be cleaved by reduction with dithiothreitol (DTT) or other reducing agents. SPDP is commonly used to attach proteins or other molecules to solid supports or to create protein conjugates. The NHS ester reacts with lysine residues on proteins, while the 2-pyridyldithio group can be used to attach another molecule via disulfide bond formation. SPDP is widely used in research and biotechnology for applications such as antibody-drug conjugates, protein immobilization, and protein labeling.'
