Background | β-Catenin is a key downstream effector in the Wnt signaling pathway. It is implicated in two major biological processes in vertebrates: early embryonic development and tumorigenesis. CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β. GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41. Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines. |

保存條件:
β-Catenin 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。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效果,請考慮使用上述檢測專用的一抗稀釋液。
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,請穿實(shí)驗(yàn)服并戴一次性手套操作。
使用說明:
請根據(jù)抗體的實(shí)際用途選擇相應(yīng)的使用方法。
1. Western檢測:
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℃緩慢搖動過夜或室溫緩慢搖動2小時(shí),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(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)操作請自行參考適當(dāng)?shù)膒rotocol進(jìn)行。
