Background Smads are a family of intracellular proteins that transmit transforming growth factor beta (TGF-beta) superfamily signals from the cell surface to the nucleus. The Smad family is divided into three subclasses: receptor regulated Smads, (Smads 1, 2, 3, 5 and 8); the common partner, (Smad4); and the inhibitory Smads, (Smads 6 and 7). The binding of TGF-beta or activin to their cognate receptor induces phosphorylation of Smads 2 and 3. The activated Smads associate with the common-mediator subunit, Smad4, and the heteromeric complex translocates into the nucleus to initiate transcription. Smad3, also known as Mothers Against Decapentaplegic homolog 3 (MADH3), shares 83% amino acid identity with Smad2, also known as Mothers Against Decapentaplegic homolog 2 (MADH2). Human Smad2 has 99% identity to mouse and rat Smad2. Human Smad3 has 99% identity to mouse and rat Smad3.

包裝清單:

產(chǎn)品編號 產(chǎn)品名稱 包裝
AF5306 SMAD2 Rabbit Polyclonal Antibody (KO Validated) 50μl
AZ050 Western一抗稀釋液 50ml
說明書 1份

保存條件:
SMAD2 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:
如果本抗體用于Western blot (WB)、免疫熒光(IF)、免疫細(xì)胞化學(xué)(ICC)等實驗,請注意回收使用過的稀釋抗體。回收的抗體通常至少可以重復(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,請穿實驗服并戴一次性手套操作。
