应用

伯胺的硫醇化试剂;在温和条件下可使硫醇去保护。通常在 pH 为 7.5 时引发耦合反应,通过酰胺键生成含伯胺的分子。在中性 pH 时可与 0.05M 羟胺发生去保护反应。用于制备酶免疫交联剂和半抗原载体分子偶联物。

其他说明

注意,与其他硫醇化试剂相比,对伯胺的酯偶合作用非常有效。此外,这种试剂可以中和伯胺的正电荷。

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
