R-Spondin 1
Featured product from Qkine
Human R-spondin 1 protein (RSPO1) is the prototypic member of the R-spondin family and is used to potentiate Wnt signalling in many organoid culture systems including intestinal and tumor (cancer) organoid culture. R-spondin 1 is also required for hematopoietic stem cell specification and cancer cell migration and survival.
13kDa highly pure, bioactive domain of human R-spondin 1 comprising the two cysteine-rich furin-like domains of R-spondin 1, which are necessary and sufficient for Wnt signalling potentiation and are the essential domains for activity in stem cell and organoid culture. Qk006 is animal-free and not glycosylated to ensure production of homogeneous protein and enhanced comparability between batches. Used to replace R-spondin conditioned media for improved reproducibility in chemically defined organoid culture media.
