Specificity / Sensitivity

Cleaved Caspase-3 (Asp175) Antibody detects endogenous levels of the large fragment (17/19 kDa) of activated caspase-3 resulting from cleavage adjacent to Asp175. This antibody does not recognize full length caspase-3 or other cleaved caspases.

该抗体能够检测 活化的Asp175 附近剪切的caspase-3大片段(17/19 kDa)。该抗体不能识别全长的caspase-3和其他caspase裂解产物。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino-terminal residues adjacent to (Asp175) in human caspase-3. Antibodies are purified by protein A and peptide affinity chromatography.

该多克隆抗体是采用合成的人源caspases Asp175氨基酸氨基末端序列相对应的肽段免疫动物后制备获得。抗体通过蛋白A和肽段亲和层析而纯化。

Caspase-3 (CPP-32, Apoptain, Yama, SCA-1) is a critical executioner of apoptosis, as it is either partially or totally responsible for the proteolytic cleavage of many key proteins such as the nuclear enzyme poly(ADP-ribose) polymerase (PARP) (1). Activation of caspase-3 requires proteolytic processing of its inactive zymogen into activated p17 and p12 fragments. Cleavage of caspase-3 requires aspartic acid at the P1 position (2).

Caspase-3 (CPP-32, Apoptain, Yama, SCA-1)是一个凋亡的关键执行者,因为它对许多关键的蛋白起着部分或全部的裂解作用,比如核酶多聚(ADP-ribose)聚合酶(PARP)(1)。caspase-3的活化需要经过其未激活的的酶原转变成活化的 p17 和 p12 片段的蛋白水解过程。caspase-3的剪切需要天门冬氨酸位于p1位点(2)。
