Recombinant Human R-Spondin 1 (21-146) Protein, His Tag

Recombinant Human R-Spondin 1 (21-146) Protein, His Tag is a high-purity fragment fused with a His tag for purification and assay compatibility. It potently activates Wnt/β-catenin signaling and is validated as an essential growth factor for intestinal and gastric organoid expansion. This protein also supports hepatic and pancreatic organoid development by maintaining epithelial stem cell populations. Premium-grade production ensures reproducibility and high activity for organoid research and regenerative medicine.
