- Human/rat/porcine/bovine FGF10 protein promotes lung organoid formation and induces branching morphology. FGF10 protein is used widely in organoid culture, embryonic stem cell (ESC) and induced-pluripotent stem cell (iPSC) differentiation, and for the study of epithelial to mesenchymal transition and tumor metastasis.High purity and bioactivity 17 kDa, bioactive domain of human fibroblast growth factor 10, animal-free (AOF) and carrier-protein free (CF).
- Human FGF-4 protein is used for the proliferation and differentiation of embryonic and induced-pluripotent and tissue (mesenchymal) stem cells and promotes neural stem cell proliferation. FGF-4 is an important component of cardiac, intestinal and other organoid culture media.High purity and bioactivity 14 kDa, bioactive domain of human fibroblast growth factor 4, animal origin free (AOF) and carrier-protein free.
- Human/bovine/porcine Gremlin 1 protein is a BMP-inhibitor present in the natural intestinal niche and provides an alternative to Noggin for optimisation of intestinal organoid culture and iPSC differentiation.Qk015 has been optimized by our experts for exceptionally high-purity production in E.coli and bioactivity. 18 kDa high purity dimeric protein, animal-free and carrier protein free
- Human EGF protein is a potent EGF-family growth factor used in many human and mouse organoid and stem cell culture systems including intestinal and tumor (cancer) organoid culture.A pure 6.3 kDa biologically active mature human epidermal growth factor. Our recombinant EGF protein is manufactured to the highest purity in E. coli and extensively tested, making it ideal for use in chemically defined iPSC, ESC and organoid culture media.
- Human R-spondin 3 protein potentiates Wnt signalling in and has been shown to function in crypt regeneration in the intestine and control stem cell and progenitor cell behaviour during kidney development. R-spondin 3 is used alongside R-spondin 1 in intestinal organoid culture systems.17kDa highly pure, bioactive domain of human R-spondin 3 comprising the two cysteine-rich furin-like domains, which are necessary and sufficient for Wnt signalling potentiation and are the essential domains for activity in stem cell and organoid culture. Animal-free and carrier-protein free.
- R-spondin 1 protein (RSPO1) is the prototypic member of the R-spondin family and is used to potentiate Wnt signaling 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.Recombinant human R-spondin 1 protein (RSPO1) protein is the bioactive domain of human R-spondin 1 comprising the two cysteine-rich furin-like domains of R-spondin 1. Those are necessary and sufficient for Wnt signaling potentiation and are the essential domains for activity in stem cell and organoid culture.This protein has a molecular weight of 13 kDa and is animal-free, carrier protein-free, and tag-free to ensure its purity with exceptional lot-to-lot consistency. Qk006 is suitable to replace R-spondin conditioned media for improved reproducibility in chemically defined organoid culture media.
- Human/mouse/rat Activin A PLUS ™ protein is an optimised biologically active truncation of the mature domain of human Activin A protein. The EC50 and activity in stem cell culture of activin A PLUS is equivalent to the full mature domain activin A.High purity 24 kDa dimer comprising truncated mature domain of activin A protein, animal-free (AF) and carrier-protein free (CF). Recombinant Activin A PLUS is designed to be manufactured at scale for cost-effective, large-scale stem cell culture applications.
- Activin A is a TGF-β family growth factor regulating embryonic development, cell proliferation, differentiation, and immune responses. Activin A is frequently used to maintain pluripotency in induced pluripotent and embryonic stem cell cultures. It is also used in many stem cell differentiation protocols, including endoderm lineage differentiation and further maturation into hepatocyte and pancreatic cells. Recombinant human/mouse/rat/bovine/porcine activin A protein is a high-purity mature bioactive dimer of 26 kDa. It is animal-free, carrier protein-free, and tag-free to ensure its purity with exceptional lot-to-lot consistency. This protein has been rigorously benchmarked against other commercial sources and extensively validated for highly reproducible stem cell culture. Qkine founder Marko Hyvönen developed the protocol for making high-purity activin A, and this protein is used at the Cambridge Stem Cell Institute. High purity mature bioactive dimer. Animal-free (AOF) and carrier-protein free (CF). Rigorously benchmarked against other commercial sources.
