Recombinant Human RSPO1 Protein

Cell Based Assay: Measured by its ability to induce Topflash reporter activity in HEK293T human embryonic kidney cells. The ED50 for this effect is 1-10ng/ml (QC verified) . Mouse intestinal organoids were cultured with EGF (Cat#orb3002493), Noggin (Cat#orb3002448) and R-spondin 1 (Cat#orb3002497) . After five days of culture, the organoids showed good morphology and germination rate. Mouse Gastric organoids were cultured with EGF (Cat#orb3002493), Wnt3a (Cat#orb3002512), Noggin (Cat#orb3002448), R-spondin 1 (Cat#orb3002497) and FGF-10 (Cat#orb3002478) . The organoids showed good morphology. Mouse bile duct organoids were cultured with EGF (Cat#orb3002493), R-spondin 1 (Cat#orb3002497), FGF-10 (Cat#orb3002478) and HGF (Cat#orb3002483) . The organoids showed good morphology. Human intestinal organoids (ipsc source) were cultured with Activin A (Cat#orb3002480), BMP-4 (Cat#orb3002515), EGF (Cat#orb3002493), Wnt3a (Cat#orb3002512), Noggin (Cat#orb3002494), R-spondin 1 (Cat#orb3002497) and FGF-4 (Cat#orb3002445) . The organoids showed good morphology. Human endometrial epithelial organoids were cultured with EGF (Cat#orb3002397) and R-spondin 1 (Cat#orb3002497) . The organoids showed good morphology.
