Description

Recombinant Human R-spondin 1 LR5 Protein, Tag-Free is an engineered variant with enhanced potency for Wnt/β-catenin pathway activation. Compared with wild-type R-Spondin 1, this version provides stronger stimulation of epithelial stem cells, enabling more robust and sustained organoid expansion. It is particularly effective in intestinal and gastric models, where long-term growth and genetic stability are required. This protein supports high-efficiency organoid culture and Wnt pathway mechanistic studies.
