- Flow , IHC / Paraffin , Immunofluorescence
Specificity / Sensitivity
Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb recognizes endogenous levels of caspase-3 protein only when cleaved at Asp175. This antibody is preferred for immunfluorescence, flow cytometry, and immunohistochemistry applications. This antibody detects non-specific caspase substrates by western blot.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp175 of human caspase-3 protein.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded Jurkat cell pellets, untreated (left) or etoposide-treated (right), using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb on SignalSlide® Cleaved Caspase-3 (Asp175) IHC Controls #8104.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded HT-29 xenograft using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb in the presence of control peptide (left) or Cleaved Caspase-3 (Asp175) Blocking Peptide #1050 (right).
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human malignant stromal tumor using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb.
Flow Cytometry
Flow cytometric analysis of Jurkat cells, untreated (blue) or etoposide-treated (green), using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb.
IF-IC
Confocal immunofluorescent analysis of HeLa cells, untreated (left) or treated with Staurosporine #9953 (1 μM, 4 hr; right), using Cleaved Caspase-3 (Asp175) (D3E9) Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Background
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 the aspartic acid residue at the P1 position (2).

文献和实验[3] 。但据报道，MCF-7 人乳腺癌细胞系中，因在 CASP-3 基因 exon 3 中存在 47bp 的缺失而不表达 caspase 3 蛋白[4] 。前体形式的 caspase-3 由一个前端功能区（prodomain）和一大一小两个催化亚单位构成。在特定的刺激比如配体受体互作、生长因子匮乏和细胞功能抑制剂等的作用下，未活化的酶原形式的 caspase-3 在 Asp-28/Ser-29（N 端功能前区）以及 Asp-175/Ser-176（大小亚基之间）被剪切活化，转变为活化的 p17 大亚
h）即可。2. 修复大法——不仅仅是「煮一煮」微波炉修复：简单易行效果好，CST 推荐使用微波炉完成修复。合适的修复液：根据抗体说明书使用合适的修复液。用柠檬酸修复后，切片需浸泡在修复液中，自然冷却；而用 EDTA 修复后，切片可直接从修复缸中取出，直接进行下一步。注：使用不同的修复方式和不同生产商的抗体检测人肺癌组织中 EGFR 的表达。第一排为 CST 的 EGF Receptor (D38B1) XP® Rabbit mAb（#4267），EDTA 的修复方式明显优于柠檬酸盐及胃蛋白
