| Background | Caspase-3 (Cysteine-aspartic acid protease 3/Casp3; also Yama, apopain and CPP32) is a 29 kDa member of the peptidase C14A family of enzymes. It is widely expressed and is an integral component of the apoptotic cascade. Caspase-3 is considered to be the major executioner caspase; that is, the primary downstream mediator of apoptotic-associated proteolysis. Active Caspase-3 is known to utilize a Cys residue to cleave multiple substrates, including PARP, proIL 16, PKC-gamma & -δ, procaspases 6, 7 and 9, and beta catenin. Human procaspase-3 is a 32 kDa, 277 amino acid (aa) protein. Normally, it is an inactive, cytosolic homodimer, but following an upstream signal that activates processing proteases, procaspase-3 undergoes proteolytic cleavage. This generates an N-terminal 175 aa p20/20 kDa subunit plus a 102 aa C-terminal p12/12 kDa subunit, followed by further processing of the p20 subunit at Asp28 to generate a final p17 subunit (aa 29 175) The p17 and p12 subunits noncovalently heterodimerize, and subsequently associate with another p17/p12 heterodimer to form an active antiparallel homodimer. The p17 subunit contains the enzyme active site (aa 161 165), with an embedded catalytic Cys which is normally nitrosylated and inactive. Full activation requires both proteolytic processing and Cys163 denitrosylation. Multiple proteases can use Caspase-3 as a substrate including Caspase-6, -8, and -10, granzyme B, and Caspase-3 itself. |

保存條件：
Caspase 3 Rabbit Polyclonal Antibody (KO Validated) -20ºC保存，Western一抗稀釋液-20ºC或4ºC保存，一年有效。Western一抗稀釋液優(yōu)先推薦4ºC保存，長期不使用可以考慮-20ºC保存，但凍融可能會(huì)導(dǎo)致出現(xiàn)輕微的渾濁和少量不溶物。
注意事項(xiàng)：
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細(xì)胞化學(xué)(ICC)等實(shí)驗(yàn)，請(qǐng)注意回收使用過的稀釋抗體�；厥盏目贵w通常至少可以重復(fù)使用5-10次。稀釋后的抗體，包括已經(jīng)使用過的稀釋抗體，請(qǐng)4℃保存。
回收后重復(fù)使用的抗體，使用方法同新鮮稀釋的抗體。如果在重復(fù)使用過程中發(fā)現(xiàn)抗體出現(xiàn)輕微混濁現(xiàn)象，可以10,000g離心1-3分鐘，取上清用于后續(xù)檢測(cè)。如果回收的抗體出現(xiàn)明顯的絮狀物或長霉長菌等情況，則可以考慮廢棄該抗體。
提供的Western一抗稀釋液也可以用于免疫熒光(IF)、免疫組化(IHC)、免疫細(xì)胞化學(xué)(ICC)等適當(dāng)用途。如果希望獲得最佳的檢測(cè)效果，請(qǐng)考慮使用上述檢測(cè)專用的一抗稀釋液。
本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用，不得用于臨床診斷或治療，不得用于食品或藥品，不得存放于普通住宅內(nèi)。
為了您的安全和健康，請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
使用說明：
請(qǐng)根據(jù)抗體的實(shí)際用途選擇相應(yīng)的使用方法。
1. Western檢測(cè)：
a. 按照推薦的稀釋比例用提供的Western一抗稀釋液稀釋抗體。
b. 把經(jīng)過封閉的蛋白膜與稀釋好的一抗4℃緩慢搖動(dòng)過夜或室溫緩慢搖動(dòng)2小時(shí)，確保稀釋的抗體至少能在搖動(dòng)的瞬間覆蓋蛋白膜。
c. 回收稀釋的一抗，4℃保存以備下次繼續(xù)使用。
d. 按照Western的實(shí)驗(yàn)步驟進(jìn)行后續(xù)的洗滌、二抗孵育、洗滌和檢測(cè)等操作。
2. 免疫染色：
可以使用生產(chǎn)的免疫染色一抗稀釋液(P0103)稀釋抗體，使用后注意回收稀釋好的一抗，
3. 其它實(shí)驗(yàn)操作請(qǐng)自行參考適當(dāng)?shù)膒rotocol進(jìn)行。
