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.

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。
