Application

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.

Other Notes

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.

The mercaptoacetyltriglycine (MAG3) chelator has been shown to stably complex technetium-99m (99mTc) for nuclear imaging and radiorhenium (186/188Re) for tumor radiation therapy studies. The bifunctional N-hydroxysuccinimidyl ester of MAG3 with S-acetyl protection (N-hydroxysuccinimidyl S-acetylmercaptoacetyltriglycinate (NHS-MAG3)) has been successfully used to

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

To develop a fluorescent ruthenium complex for biosensing, we synthesized a novel sulfhydryl-reactive compound, 4-bromophenanthroline bis-2,2'-dipyridine Ruthenium bis (hexafluorophosphate). The synthesized Ru(II) complex was crosslinked with thiol-modified protein G to form a universal reagent for fluorescent immunoassays. The resulting Ru(II)-protein

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
