Background | The Stat1 transcription factor is activated in response to a large number of ligands and is essential for responsiveness to IFN-α and IFN-γ. Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation, and DNA binding. Stat1 protein exists as a pair of isoforms, Stat1α (91 kDa) and the splice variant Stat1β (84 kDa). In most cells, both isoforms are activated by IFN-α, but only Stat1α is activated by IFN-γ. The inappropriate activation of Stat1 occurs in many tumors. In addition to tyrosine phosphorylation, Stat1 is also phosphorylated at Ser727 through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway in response to IFN-α and other cellular stresses. Serine phosphorylation may be required for the maximal induction of Stat1-mediated gene activation. |

保存条件:
Phospho-STAT1 (Tyr701) Rabbit Polyclonal Antibody -20ºC保存,Western一抗稀释液-20ºC或4ºC保存,一年有效。Western一抗稀释液优先推荐4ºC保存,长期不使用可以考虑-20ºC保存,但冻融可能会导致出现轻微的浑浊和少量不溶物。
注意事项:
如果本抗体用于Western blot (WB)、免疫荧光(IF)、免疫细胞化学(ICC)等实验,请注意回收使用过的稀释抗体。回收的抗体通常至少可以重复使用5-10次。稀释后的抗体,包括已经使用过的稀释抗体,请4℃保存。
回收后重复使用的抗体,使用方法同新鲜稀释的抗体。如果在重复使用过程中发现抗体出现轻微混浊现象,可以10,000g离心1-3分钟,取上清用于后续检测。如果回收的抗体出现明显的絮状物或长霉长菌等情况,则可以考虑废弃该抗体。
提供的Western一抗稀释液也可以用于免疫荧光(IF)、免疫组化(IHC)、免疫细胞化学(ICC)等适当用途。如果希望获得最佳的检测效果,请考虑使用上述检测专用的一抗稀释液。
本产品仅限于专业人员的科学研究用,不得用于临床诊断或治疗,不得用于食品或药品,不得存放于普通住宅内。
为了您的安全和健康,请穿实验服并戴一次性手套操作。
使用说明:
请根据抗体的实际用途选择相应的使用方法。
1. Western检测:
a. 按照推荐的稀释比例用碧云天提供的Western一抗稀释液稀释抗体。
b. 把经过封闭的蛋白膜与稀释好的一抗4℃缓慢摇动过夜或室温缓慢摇动2小时,确保稀释的抗体至少能在摇动的瞬间覆盖蛋白膜。
c. 回收稀释的一抗,4℃保存以备下次继续使用。
d. 按照Western的实验步骤进行后续的洗涤、二抗孵育、洗涤和检测等操作。具体操作可以参考如下网页:
