Aplicação
Thiolating reagent for primary amines; thiol can be deprotected under mild conditions. Typically, couples initially to a molecule containing primary amine by amide bond buffered at pH 7.5. Deprotection may be accomplished with 0.05 M hydroxylamine at neutral pH. Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates.
Outras notas
Note that the ester couples very efficiently to primary amines compared to other thiolating reagents. In addition, this reagent will neutralize original amine positive charge.
