Application

Reactant for:
  • Synthesis of glutathione-sensitive cross-linked polyethylenimine gene vector
  • Preparation of cyclodextrin-containing polymers designed for gene delivery
  • Crosslinking of chick oviduct progesterone-receptor subunits

Caution

The reagant is readily hydrolyzed at neutral pH. Avoid use of reducing agents during coupling reactions.

Other Notes

Note that the amidine linkage preserves original primary amine positive charge. The disulfide linkage is cleavable by mild reduction. Incorporates an eight atom linker.

A cleavable cross-linking reagent, dimethyl-3,3'-dithiobispropionimidate, was used to study the molecular organization of adrenocortical cytochrome P-450scc. Extensive cross-linking was found to occur, resulting in the formation of heterologous oligomers up to octamer. The covalently cross-linked complex of adrenocortical cytochrome P-450scc
