Human R-Spondin 1 / RSPO1 Protein (aa 1-146, His Tag)

Species : Human

Synonyms : CRISTIN3,R-Spondin 1,RSPO

Host : HEK293 Cells

Purity :> 98 % as determined by SDS-PAGE

Activity : 1. Measured by its ability to bind recombinant mouse CD36 in a functional ELISA.
2. Measured by its ability to induce activation of £]-catenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The ED50 for this effect is typically 0.1-0.5 £gg/mL in the presence of 5 ng/mL recombinant mouse Wnt3a.
