识别内源性人Caspase-1全长和活化的形式(p20片段)

Caspase-1是最能描述的炎症性caspase。它处理细胞因子白介素-1B(IL-1β)和IL-18,并诱导焦细胞凋亡。 Caspase-1被称为炎症小体的多蛋白复合物激活,以响应通过独特的炎症小体检测到的多种刺激。 NLRC4响应胞质鞭毛蛋白,鼠NLRP1b响应炭疽致死毒素,AlM2响应细胞质DNA,NLRP3响应多种激动剂,包括晶体。

实验方法:

    THP1细胞用0.5μMPMA(产品编号AG-CN2-0010)诱导分化3h后,以5uM Nigericin 活化(lane2)或不激活(lane1)处理1h(产品编号AG-CN2-0020)。收集30uL细胞上清,在还原条件下进行SDS-PAGE 电泳分离,转移至硝酸纤维素膜并以anti-caspase-1(p20)(human),mAb(Bally-1)孵育。最后进行化学发光检测。
