Recombinant Human RSPO1 Protein

SKU: orb3002497

Description

Recombinant Human R-spondin-1 is produced by our Mammalian expression system and the target gene encoding Ser21-Ala263 is expressed with a 6His tag at the C-terminus.

Key Properties

• Expression System: Human Cells
• Biological Activity: 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. Data were kindly provided by Biorbyt's customer. Thanks for her contribution.

Storage & Handling

• Storage: Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
• Form/Appearance: Lyophilized
• Buffer/Preservatives: 0.2 μm filtered solution of PBS,4%Mannitol,pH 7.4.
• Reconstitution: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Expiration Date: 6 months from date of receipt.
