概述
SATA is the reagentfor introducing protected sulfhydryls into proteins, peptides and other molecules. They are the N-hydroxysuccinimide (NHS) esters of S-acetylthioacetic and propionic acid. A stable, covalent amide bond is formed from the reaction of the NHS ester with primary amines. The amine reacts with the NHS ester by nucleophilic attack, with N-hydroxysuccinimide being released as a by-product. Deprotection (deacylation) to generate a sulfhydryl for use in cross-linking and other applications is accomplished using hydroxylamine HCl.
特点
- Reaction conditions are mild and non-denaturing;The reaction is specific toward primary amines;Sulfhydryl groups are introduced in a protected form, allowing the modified molecule to be stored indefinitely and then later treated with hydroxylamine to expose the labile sulfhydryl group for final conjugation reactions.
