一般說明

半胱天冬酶-1,也称为IL-1β转化酶(ICE),是一种酶,可裂解炎性细胞因子IL-1β和IL-18,从而释放成熟的活性肽。半胱天冬酶-1对于防御病原体很重要,并且它也参与细胞凋亡的诱导。来自半胱天冬酶-1缺陷小鼠的胸腺细胞对Fas介导的细胞凋亡具有抗性,并且半胱天冬酶-1与秀丽隐杆线虫的细胞死亡基因CED-3相似。半胱天冬酶-1是由两个反平行异二聚体组成的异四聚体,每个异二聚体由20 kDa(p20)和10 kDa(p10)亚基形成。该酶具有Tyr-Val-Ala-Asp(YVAD)的优选切割位点。半胱天冬酶-1在脾脏和肺中高表达,而在大脑中则不存在。

特異性

其他同源性:小鼠、大鼠、犬、猪和猫。(92%序列同源性)。
该抗体可识别半胱天冬酶1的p20亚基。由于92%的序列同源性,该抗体可与半胱天冬酶5发生交叉反应。此外,该抗体可识别还原型人半胱天冬酶1亚型的P45酶原(~45 kDa)和p20亚基(~20 kDa)。

免疫原

与人半胱天冬酶1的p20亚基相对应的KLH偶联的线性肽。
表位:p20亚基

應用

免疫组化分析:代表批次的1:1,000稀释液在人脾脏组织中检测到半胱天冬酶1。此外,代表批次的1:4,000稀释液在人结肠组织中检测到半胱天冬酶1。
抗半胱天冬酶1抗体是一种高度特异性的兔多克隆抗体,靶向半胱天冬酶1 & 已通过蛋白质印迹&IHC(石蜡)进行测试。
研究子类别
半胱天冬酶

品質

通过蛋白质印迹对THP-1细胞裂解液进行了评估。

蛋白质印迹分析:5 µg/mL的该抗体在10 µg THP-1细胞裂解液中检测到半胱天冬酶1。

標靶描述

观测值〜45 kDa。已知存在10-45 kDa之间的五个亚型。该抗体可识别还原的人半胱天冬酶1亚型的P45酶原(~45 kDa)和p20亚基(~20 kDa)。
