应用： 用于蛋白质巯基的氰基化试剂; 用于制备蛋白-多糖偶联物。 用于多糖树脂的激活剂以及在保持内毒素活性的同时与脂多糖的偶联。 Cyanylation reagent for protein sulfhydryl groups; used to prepare protein-polysaccharide conjugates.Activating agent for polysaccharide resins and conjugation of lipopolysaccharides while retaining endotoxic activity. 1-Cyano-4-dimethylaminopyridinium tetrafluoroborate is an organic cyanylating agent also termed CDAP. It is a unique cystine-labeling reagent due to its reactive nature under acidic conditions. This feature provides CDAP an advantage over other sulfhydryl labeling agents, as it can avoid potential thiol-disulfide exchange.
