Description

Recombinant Human R-Spondin 1 Protein, His Tag is a recombinant full-length Wnt signaling enhancer fused with a His tag. It strongly potentiates Wnt/β-catenin activity, essential for epithelial stem cell proliferation and organoid culture. R-Spondin 1 is required in most epithelial organoid protocols, particularly for intestinal and colonic organoids, where it sustains long-term expansion. The His tag supports assay flexibility and reliable purification, ensuring reproducibility across organoid and developmental biology applications.
