RSPO1 Protein, Human, Recombin

蛋白长度：A DNA sequence encoding the amino acids (Met 1-Ala 146) of human RSPO1 (NP_001033722.1) was expressed, fused with a polyhistidine tag at the C-terminus.

性质：

表达系统：HEK293 Cells

种属：Human

氨基酸序：Met1-Ala146

标签类型：C-His

分子量：The secreted recombinant human RSPO1 (aa 1-146) comprises 137 amino acids and has a predicted molecular mass of 14 kDa. As a result of glycosylation, rhRSPO1 migrates as an approximately 23 kDa band in SDS-PAGE under reducing conditions.

活性：1. Measured by its ability to bind recombinant mouse CD36 in a functional ELISA. 2. Measured by its ability to induce activation of β-catenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The EDfor this effect is typically 0.1-0.5 μg/mL in the presence of 5 ng/mL recombinant mouse Wnt3a.

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.

基因名称：R-spondin 1

通用名：RSPO1

蛋白序参考：NP_001033722.1

总结：RSPO1 gene is a member of the R-spondin family. It encodes RSPO1 which is known as a secreted activator protein with two cystein-rich, furin-like domains and one thrombospondin type 1 domain. In mice, RSPO1 induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. This protein is an activator of the beta-catenin signaling cascade, leading to TCF-dependent gene activation. RSPO1 acts both in the canonical Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway, probably by acting as an inhibitor of ZNRF3, an important regulator of the Wnt signaling pathway. It also acts as a ligand for frizzled FZD8 and LRP6.

形式：Lyophilized

纯度：> 98 % as determined by SDS-PAGE.

储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.

储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
