產(chǎn)品信息
Wnt糖蛋白是存在于多種生物體內(nèi)的一種細(xì)胞外配體，Wnt作為形態(tài)發(fā)生素通過激發(fā)細(xì)胞內(nèi)遠(yuǎn)離信號發(fā)送區(qū)域的濃度依賴反應(yīng)控制胚胎形態(tài)發(fā)育。Wnt通路調(diào)節(jié)動(dòng)物發(fā)育過程中的多個(gè)重要環(huán)節(jié)，例如細(xì)胞增殖、細(xì)胞遷徙及細(xì)胞分化。Wnt蛋白通過自分泌或旁分泌作用與位于細(xì)胞膜上的受體相結(jié)合，激活細(xì)胞內(nèi)信號通路調(diào)節(jié)靶基因的表達(dá)，對細(xì)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(chǎn)品簡介
wnt通路是細(xì)胞增殖分化的關(guān)鍵調(diào)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(dá)調(diào)節(jié)、 細(xì)胞遷移粘附、細(xì)胞極化等過程，同時(shí)還與其它信號通路存在交叉協(xié)同。Wnt/β-catenin通路在進(jìn)化過程中高度保守，此通路的主要分子構(gòu)成及相關(guān)調(diào) 控機(jī)制已得到基本闡明。對神經(jīng)系統(tǒng)而言已有足夠證據(jù)顯示此通路參與了對神經(jīng)前體細(xì)胞增殖， 分化以及決定細(xì)胞命運(yùn)的調(diào)控。
Wnt-3a干細(xì)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(jīng)干細(xì)胞的定向分化的調(diào)控作用表現(xiàn)的十分明顯。小鼠WNT-3a 干細(xì)胞生長分化因子蛋白包含328個(gè)氨基酸。

StemRD W5A-H-100 WNT-5a,mouse,100ug 保存方法
The lyophilized protein is stable for at least 6 months if stored at -80 degreeC. Reconstituted protein is stable for at least two weeks at 4 degree C, but should be stored in aliquots at -80 degree C for longer term. Avoid repeated freeze and thaw.
StemRD W5A-H-100 WNT-5a,mouse,100ug 產(chǎn)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。
