N-Succinimidyl-p-and m-(2-nitrovinyl)-benzoates (SNVB) were introduced as heterobifunctional conjugating reagents for immunoassay. These reagents smoothly react with SH-compounds, such as cysteine or mercaptopropionic acid, in acidic media, then with alanine under slightly basic conditions to yield the corresponding benzoylalanine derivatives. On the basis of these model experiments, the feasibility of practical use of these reagents is discussed.
N-琥珀酰亚胺基对位和间位(2-硝基乙烯基)苯甲酸酯(SNVB)被引入作为免疫测定中的异双功能偶联剂。这些试剂在酸性介质中与SH化合物(如半胱氨酸或巯基丙酸)顺利反应,然后在略碱性条件下与丙氨酸反应,生成相应的苯甲�丙氨酸衍生物。基于这些模型实验,讨论了这些试剂在实际应用中的可行性。
