StemRD DKK-100 DKK-1,Human,500ug 產(chǎn)品簡介
DKK-1是重組人Dickkopf相關(guān)蛋白1的簡稱，是DKK蛋白家族（DKK1-4）的一員。DKK最初被認為是非洲爪蟾蜍的前期成形細胞。通過機理 研究發(fā)現(xiàn)DKK-1通過與共同受體LRP5/6一起形成抑制復(fù)合物，可以有效抑制Wnt/β-catenin信號通路。研究人員發(fā)現(xiàn)敲除DKK-1基因小 鼠的腦部無法形成，從而證實Wnt/β-catenin信號通路的抑制在脊椎動物的后模式與前模式發(fā)展中必不可少。
StemRD公司生產(chǎn)的人重組StemRD DKK-500 DKK-1,Human,500ug 蛋白干細胞生長分化調(diào)整因子來源于人的293細胞，是含有235個氨基酸片段，分子量為3740kDa的糖蛋白。通過諸如HPLC等一系列色譜分析方法對其進行純化。
Wnt 信號轉(zhuǎn)導通路參與了多種生物學過程的調(diào)控, 包括胚胎的生長和形態(tài)發(fā)育、組織的穩(wěn)定、能量代謝的平衡以及干細胞的維持。Wnt 通路的失調(diào)與人類重大疾病有密切聯(lián)系。
近年來人們在對干細胞的研究中發(fā)現(xiàn),Wnt 信號通路對于表皮干細胞、腸干細胞、造血干細胞、神經(jīng)干細胞、胚胎干細胞以及腫瘤干細胞的維持都起著重要的調(diào)控作用。所以, 深入研究Wnt 信號通路的調(diào)控機理, 尋找藥物治療的靶蛋白,是近年來生物學和醫(yī)學研究的熱門領(lǐng)域。

repeated freeze and thaw.

StemRD DKK-500 DKK-1,Human,500ug 產(chǎn)品英文描述
DKK-1, Dickkopf-related protein-1, is a member of the DKK protein family which includes DKK-1 through DDK-4. DKK was originally identified as a head-forming molecule in Xenopus. Mechanistic studies showed that DKK-1 inhibits the Wnt /β-catenin signaling pathway by forming inhibitory complexes with co-receptor LRP5/6. Inhibition of Wnt/β-catenin signaling is essential for posterior patterning and anterior development in vertebrates, supported by the discovery that DKK-1 knockout mice lack head formation.
StemRD expressed recombinant human Dkk-1,human DKK-500,500ug in human 293 cells as a 37-40 kDa glycoprotein containing 235 amino-acid residues. It is purified by aseries of chromatography including HPLC.
•Dkk-1,human DKK-500,500ug Purity: Greater than 90% as determined by SDS-PAGE analysis
•Dkk-1,human DKK-500,500ug Biological Activity: The activity was determined by using a TCF reporter gene assay in cultured human cells. The IC50 ranges from 100 - 500 ng/ml in the inhibition of 100 ng/mL WNT-3a activity. Activity in other assays should be determined by each individual setting.
