Applicazioni
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.
Altre note
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.

Immuno-enzymosomes are tumor-specific immunoliposomes bearing enzymes on their surface. These enzymes are capable of converting relatively nontoxic prodrugs into active cytostatic agents. The enzyme beta-glucuronidase (GUS)4 was coupled to the external surface of immunoliposomes directed against ovarian carcinoma cells. This

The intracellular activity of certain antiviral agents, including antisense oligonucleotides, acyclic nucleoside phosphonates, and protease inhibitors, is enhanced when they are delivered in liposome-encapsulated form. In this chapter we describe the preparation of pH-sensitive liposomes encapsulating antisense oligonucleotides, ribozymes, and
