Wnt糖蛋白是存在于多種生物體內的一種細胞外配體，Wnt作為形態(tài)發(fā)生素通過激發(fā)細胞內遠離信號發(fā)送區(qū)域的濃度依賴反應控制胚胎形態(tài)發(fā)育。Wnt通路調節(jié)動物發(fā)育過程中的多個重要環(huán)節(jié)，例如細胞增殖、細胞遷徙及細胞分化。Wnt蛋白通過自分泌或旁分泌作用與位于細胞膜上的受體相結合，激活細胞內信號通路調節(jié)靶基因的表達，對細胞的增殖、分化、遷移、極性化和凋亡起到重要作用。

StemRD W5A-H-100 WNT-5a,mouse,100ug 產品簡介
wnt通路是細胞增殖分化的關鍵調控環(huán)節(jié)，在胚胎發(fā)育和腫瘤發(fā)生中起著重要作用。wnt途徑參與了基因表達調節(jié)、細胞遷移粘附、細胞極化等過程，同時還與其它信號通路存在交叉協(xié)同。Wnt/β-catenin通路在進化過程中高度保守，此通路的主要分子構成及相關調控機制已得到基本闡明。對神經系統(tǒng)而言已有足夠證據(jù)顯示此通路參與了對神經前體細胞增殖，分化以及決定細胞命運的調控。
Wnt-3a干細胞生長分化因子是Wnt基因家族中重要成員，zui近的一些研究發(fā)現(xiàn)， Wnt-3a信號蛋白對神經干細胞的定向分化的調控作用表現(xiàn)的十分明顯。小鼠WNT-3a 干細胞生長分化因子蛋白包含328個氨基酸。

StemRD W5A-H-100 WNT-5a,mouse,100ug 產品英文描述
WNT-3a is a member of the WNT family of signaling proteins that play a key role in embryonic development and the integrity of adult tissues. StemRD W5A-H-100 WNT-5a,mouse,100ug is a prototypic canonical WNT that signals through the β-catenin pathway. The predicted size of mouse StemRD W5A-H-100 WNT-5a,mouse,100ug is a monomeric protein containing 333 amino acid residues. Due to glycosylation, it migrates at an apparent molecular weight of 40 kDa by SDS-PAGE analysis under nonreducing conditions. StemRD’s product W5A-H-100 WNT-5a,mouse,100ug is expressed from a mouse cell line overexpressing mouse WNT-3a. Purification is performed with a proprietary process that is distinct from the published method.
?StemRD W5A-H-100 WNT-5a,mouse,100ug Purity: Greater than 90% as determined by SDS-PAGE analysis
?StemRD W5A-H-100 WNT-5a,mouse,100ug Biological Activity: The activity was determined by using a TCF reporter gene assay in NIH3T3 cells. The EC50 ranges from 50 - 150 ng/ml. Country of Origin USA。
