Methyltetrazine-PEG 4-STP Ester是一种胺反应性水溶性标记试剂，用于在水性介质中修饰蛋白质、抗体和其他含胺生物聚合物。与甲基四嗪-磺基NHS酯相比，甲基四嗪-PEG 4-STP酯在水性介质中以慢得多的速率进行水解，从而允许在水性介质中更有效地标记生物分子。

Methyltetrazine-PEG4-STP Ester is an amine-reactive, water-soluble labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers in aqueous media. Methyltetrazine-PEG4-STP Ester undergoes hydrolysis in aqueous media at much slower rate compared to Methyltetrazine-Sulfo NHS Ester allowing for more efficient labeling of biomolecules in aqueous media. The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary TCO-containing molecules. The aqueous solubility of this reagent is substantially enhanced by a hydrophilic polyethylene glycol (PEG) spacer arm.4-Sulfo-2,3,5,6-tetrafluorophenyl (STP) esters is another type of carboxylic acid derivative that react with primary amines forming covalent amide bond. The amine linkage bond is identical to one formed by the reaction between primary amines and NHS esters or sulfo-NHS esters. However, in most cases, STP ester displays much better stability toward hydrolysis in aqueous media resulting in more efficiency and better reproducible labeling of biopolymers.
