Category Autophagy Signaling
Background Autophagy is a catabolic process for the autophagosomic-lysosomal degradation of proteins activated in response to nutrient deprivation and in neurodegenerative conditions. One of the proteins critical to this process is Beclin-1, the mammalian orthologue of the yeast autophagy protein Apg6/Vps30. Beclin-1 can complement defects in yeast autophagy caused by loss of Apg6 and can also stimulate autophagy when overexpressed in mammalian cells. Mammalian Beclin-1 was originally isolated in a yeast two-hybrid screen for Bcl-2 interacting proteins and has been shown to interact with Bcl-2 and Bcl-xL, but not with Bax or Bak. While Beclin-1 is generally ubiquitously expressed, research studies have shown it is monoallelically deleted in 40-75% of sporadic human breast and ovarian cancers. Beclin-1 is localized within cytoplasmic structures including the mitochondria, although overexpression of Beclin-1 reveals some nuclear staining and CRM1-dependent nuclear export. Investigators have demonstrated that Beclin-1-/- mice die early in embryogenesis and Beclin-1-/+ mice have a high incidence of spontaneous tumors. Stem cells from the null mice demonstrate an altered autophagic response, although responses to apoptosis appeared normal. Researchers have also found that overexpression of Beclin-1 in virally infected neurons in vivo resulted in significant protection against Sindbis virus-induced disease and neuronal apoptosis.

保存條件:
Beclin 1 Rabbit Polyclonal Antibody (KO Validated) -20ºC保存,Western一抗稀釋液-20ºC或4ºC保存,一年有效。Western一抗稀釋液優先推薦4ºC保存,長期不使用可以考慮-20ºC保存,但凍融可能會導致出現輕微的渾濁和少量不溶物。
注意事項:
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細胞化學(ICC)等實驗,請注意回收使用過的稀釋抗體;厥盏目贵w通常至少可以重復使用5-10次。稀釋后的抗體,包括已經使用過的稀釋抗體,請4℃保存。
回收后重復使用的抗體,使用方法同新鮮稀釋的抗體。如果在重復使用過程中發現抗體出現輕微混濁現象,可以10,000g離心1-3分鐘,取上清用于后續檢測。如果回收的抗體出現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)、免疫細胞化學(ICC)等適當用途。如果希望獲得最佳的檢測效果,請考慮使用上述檢測專用的一抗稀釋液。
本產品僅限于專業人員的科學研究用,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。
為了您的安全和健康,請穿實驗服并戴一次性手套操作。

使用說明:
請根據抗體的實際用途選擇相應的使用方法。
1. Western檢測:
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. 把經過封閉的蛋白膜與稀釋好的一抗4℃緩慢搖動過夜或室溫緩慢搖動2小時,確保稀釋的抗體至少能在搖動的瞬間覆蓋蛋白膜。
c. 回收稀釋的一抗,4℃保存以備下次繼續使用。
d. 按照Western的實驗步驟進行后續的洗滌、二抗孵育、洗滌和檢測等操作。
2. 免疫染色:
可以使用生產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. 其它實驗操作請自行參考適當的protocol進行。
