描述：

Sox2 (D6D9) XP^® Rabbit mAb（Alexa Fluor^® 555偶联）可以识别内源性的Sox2蛋白。多克隆抗体是通过一种合成的肽段去免疫动物产生。这种合成的肽段与邻近人源Sox2蛋白Gly179的氨基酸残基序列一致。Cell Signaling Technology公司抗体与Alexa Fluor^® 555 荧光染料偶联，对人细胞经免疫荧光分析进行内部测试。本抗体与无偶联的Sox2 (D6D9) XP^® Rabbit mAb #3579有同样的种属交叉反应性。胚胎干细胞分离自囊泡的内细胞团，并有独特的多分化潜能和自我更新潜能。Sox2是一种对于保持细胞多潜能性起关键作用的转录因子(1)。Sox2, Oct-4和Nanog在调控网络中协同作用(1-3)。表达Sox2 或 Oct-4的siRNA诱导沉默会导致细胞多潜能性的丢失(4,5)。染色质免疫沉淀实验显示Sox2和 Oct-4能结合到数千个基因的调控位点，显示了这些转录因子在胚胎早期发育中的重要性(6,7)。最近的研究发现Sox2基因在肺癌和食管鳞癌中扩增（8）.

Homology

Species predicted to react based on 100% sequence homology: Monkey, Bovine, Dog, Horse

Specificity / Sensitivity

Sox2 (D6D9) XP^® Rabbit mAb (Alexa Fluor^® 555 Conjugate) detects endogenous levels of Sox2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to amino acids surrounding Gly179 of human Sox2.

Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor^® 555 fluorescent dye and tested in-house for immunofluorescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated Sox2 (D6D9) XP^® Rabbit mAb #3579.

Background

Embryonic stem cells are derived from the inner cell mass of the blastocyst and are unique in their pluripotent capacity and potential for self-renewal. Sox2 is one of a set of transcription factors that are crucial for the maintenance of pluripotency (1). Sox2, Oct-4, and Nanog cooperate in this network (1-3) and siRNA knockdown of either Sox2 or Oct-4 results in loss of pluripotency (4,5). Chromatin immunoprecipitation experiments have shown that Sox2 and Oct-4 bind to thousands of gene regulatory sites, highlighting the importance of these transcription factors in early embryonic development (6,7). It has recently been shown that Sox2 is amplified in lung and esophageal squamous cell tumors (8).
