General description

DST is a homobifunctional crosslinker that contains amine-reactive N-hydroxysuccinimide (NHS) ester groups and is periodate cleavable. DST is commonly used for conjugating radiolabeled ligands to cell surface receptors. DST must first be dissolved in an organic solvent, such as DMSO or DMF, then added to the aqueous reaction mixture. DST is lipophilic, membrane-permeable and does not possess a charged group, which makes it useful for intracellular and intramembrane protein conjugation.

Features and Benefits

  • Reactive groups: NHS ester (both ends)
  • Reactive towards: amino groups (primary amines)
  • Soluble in DMSO or DMF at a concentration of ~10 mM (3 mg/mL)
  • Cleavable by sodium meta-periodate (Part No. 20504)
  • Ideal for applications in which crosslink cleavability is desired without disturbing protein disulfide bonds

Caution

This product is sensitive to moisture. The vial is packaged in a resealable bag with a desiccant to reduce exposure to moisture. After cold storage, equilibrate the vial to room temperature before opening to reduce condensation inside the vial. Make fresh solutions. Storage of stock solutions is not recommended. After use, return the vial to the resealable bag. Close the bag and store the product at the recommended temperature.

Two novel cross-linkers, disuccinimidyl tartarate (DST) and N,N'-bis(3-succinimidyloxycarbonylpropyl)tartaramide (SPT), have been synthesized. These reagents span 6 and 18 A, respectively, between functional groups and contain a vic-glycol bond which can be cleaved with periodate under mild reaction conditions. Both DST

A heterobifunctional reagent, N-succinimidyl 3-(2-pyridyldithio)propionate, was synthesized. Its N-hydroxysuccinimide ester group reacts with amino groups and the 2-pyridyl disulphide structure reacts with aliphatic thiols. A new thiolation procedure for proteins is based on this reagent. The procedure involves two steps.
