产品英文名称:R-spondin-1, human
产品中文名称:人重组R-spondin-1蛋白
R-spondin-1, human产品介绍:
R-spondin-1是权威WNT信号通路的天然增强剂。当与激活β-catenin信号通路的WNT蛋白联合使用时,R-spondin-1能通过与LGR5和LGR4融合而有效提高权威WNT蛋白的活性。
向小鼠注射重组R-spondin-1蛋白可以激活β-catenin信号通路和肠道下皮细胞的增殖,为临床改善化疗诱导结肠炎操作提供了基础和依据。
全片段R-spondin-1的预测分子量是25.6kDa,而且在特异性条件下,由于SDS-PAGE葡糖基化的影响,分子量可达到约39kDa。StemRD公司的R-spondin-1是由人293细胞作为分泌蛋白,再由一系列色谱分析法纯化而来。
R-spondin-1, human产品英文简述:
R-spondin-1 is a natural enhancer of the canonical WNT pathway. When used together with WNT proteins that activate the beta-catenin pathway, Rspondin-1 enhances the activity of canonical WNT proteins by binding to LGR5 and LGR4 (refs.) Injection of recombinant R-Spondin-1 into mouse causes activation of the-catenin pathway and proliferation of intestinal crypt cells, which forms the basis for a clinical trial in amelioration of chemotherapy-induced colitis. The Predicted MW of full-length R-Spondin-1 is 25. 6 kDa, and due to glycosylation it runs on SDS-PAGE at ~39 kDa under reducing conditions. StemRD’s R-Spondin-1 is produced in human 293 cells as a secreted protein (without tag) and purified by a series of chromatography.
• Purity:Greater than 90% as determined by SDS-PAGE analysis
• Biological Activity:The activity was determined by using a TCF reporter gene assay in cultured
human cells. The EC50 ranges from 5 - 20 ng/ml in the presence of 10ng/mL human WNT-3a. Activity in other assays should be determined by each individual setting
• For Research Use Only. Not for Use in Human
