灵敏可靠的ELISA试剂盒，用于检测血浆、血清和尿液样本中的缓激肽

缓激肽（Bradykinin）于1949年被发现，由血浆中的球蛋白前体在蛋白酶的作用下生成。它的名字表明它会促使肠道缓慢运动。早在1909年，人们就注意到在尿液中发现的物质（后来被确定为激肽）具有降压作用。激肽是血管舒张、血管通透性、NO 释放和花生四烯酸动员的效应物。它们是血压、肾功能和心脏功能的重要调节因子，并且还参与炎症反应。

缓激肽是通过血液中激肽释放酶系统的作用（与凝血级联有关）从血球蛋白激肽原HK 产生的，但也可以在其他组织和器官中产生。除激肽释放酶外，其他蛋白酶如纤溶酶也可释放缓激肽。几种肽酶可以降解激肽，包括血管紧张素转化酶(ACE)，这是一种可将血管紧张素 I 转化为血管紧张素 II 并破坏缓激肽的金属蛋白酶。血浆缓激肽迅速降解为较小的稳定肽(BK1-5)形式。
