Recombinant Human RSPO1 Protein (Ser21-Ala263)
Product Description
Cat
IMP-9818
Official Symbol
RSPO1
Product Overview
Recombinant human R-Spondin 1 protein (Ser21-Ala263) without tag was expressed in Chinese Hamster Ovary cell line.
Description
This gene encodes a secreted activator protein with two cysteine-rich, furin-like domains and one thrombospondin type 1 domain. The encoded protein is a ligand for leucine-rich repeat-containing G-protein coupled receptors (LGR proteins) and positively regulates the Wnt signaling pathway. In mice, the protein induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. Alternative splicing results in multiple transcript variants.

Bio-activity
Measured by its ability to induce Topflash reporter activity in HEK293T human embryonic kidney cells. The ED50 for this effect is 1.00-10.0 ng/mL in the presence of 5 ng/mL Recombinant Mouse Wnt-3a.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
Reconstitute at 100 μg/mL in PBS containing at least 0.1% human or bovine serum albumin.
