StemRD DKK-100 DKK-1,Human,500ug 产品简介
DKK-1是重组人Dickkopf相关蛋白1的简称，是DKK蛋白家族（DKK1-4）的一员。DKK最初被认为是非洲爪蟾蜍的前期成形细胞。通过机理 研究发现DKK-1通过与共同受体LRP5/6一起形成抑制复合物，可以有效抑制Wnt/β-catenin信号通路。研究人员发现敲除DKK-1基因小 鼠的脑部无法形成，从而证实Wnt/β-catenin信号通路的抑制在脊椎动物的后模式与前模式发展中必不可少。
StemRD公司生产的人重组StemRD DKK-500 DKK-1,Human,500ug 蛋白干细胞生长分化调整因子来源于人的293细胞，是含有235个氨基酸片段，分子量为3740kDa的糖蛋白。通过诸如HPLC等一系列色谱分析方法对其进行纯化。
Wnt 信号转导通路参与了多种生物学过程的调控, 包括胚胎的生长和形态发育、组织的稳定、能量代谢的平衡以及干细胞的维持。Wnt 通路的失调与人类重大疾病有密切联系。
近年来人们在对干细胞的研究中发现,Wnt 信号通路对于表皮干细胞、肠干细胞、造血干细胞、神经干细胞、胚胎干细胞以及肿瘤干细胞的维持都起着重要的调控作用。所以, 深入研究Wnt 信号通路的调控机理, 寻找药物治疗的靶蛋白,是近年来生物学和医学研究的热门领域。

StemRD DKK-500 DKK-1,Human,500ug 产品英文描述
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.
