This version of recombinant zebrafish FGF2 is used by the core facility at the Cambridge Stem Cell Institute, UK and historically by many of the stem cell groups based at University of Cambridge.
- 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/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/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 IGF-1 protein (IGF-I), insulin-like growth factor 1, is used in the maintenance of human pluripotent stem cells and is necessary for cell growth in the absence of insulin1. IGF-1 promotes the proliferation of many cell types, including mesenchymal stem cells, in vitro.Highly pure and bioactive 8 kDa IGF-1 protein, animal-free (AF) and carrier-protein free (CF)
- Human IGF-1 LR3, insulin-like growth factor long arginine 3, protein is a synthetic analog of IGF-1. The substitutions include an Arginine substitution and an N-terminal protein extension. Consequently, IGF-1 LR3 has improved biological potency and extended half-life.Highly pure and bioactive 9 kDa IGF-1 LR3 protein monomer, animal-free (AF) and carrier-protein free (CF). IGF-1 LR3 is often used in the maintenance of human pluripotent stem cells [1].
- Mouse LIF (murine leukemia inhibitory factor) protein maintains the pluripotency and self-renewal of mouse embryonic and induced pluripotent stem cells. Qkine recombinant mouse LIF protein is animal-free and carrier-protein free for highly reproducible results. Bioactivity was tested by colony formation assay and determination of Nanog expression.1
- Human LIF (leukemia inhibitory factor) protein suppresses the differentiation of murine embryonic stem cells (ESCs) and is widely used in ESC and iPSC culture.1 Qkine human LIF protein is high purity and animal and carrier-protein free for reproducible results.
- Human NRG-1 protein (Neuregulin 1) is frequently used in the maintenance of human pluripotent stem cells. In addition to its widespread use in stem cell culture media, NRG-1 (also known as Heregulin-β1 , HRG-1) has essential roles in vivo including in nervous system, cardiac, and mammary gland development; cancer biology and neurological disorders.7.5 kDa highly pure, bioactive domain of human NRG-1, comprised of the β isoform of the EGF-like domain of NRG-1 (HRG1-B1). This NRG-1 protein monomer is animal-free (AF) and carrier-protein free (CF).
- Human noggin is a bone morphogenetic protein (BMP) family antagonist used in the culture of intestinal, pancreatic, lung and tumor-derived organoids, maintenance of undifferentiated embryonic stem cells and for stem cell differentiation into neural and microglial lineages.Qkine human noggin protein is a highly pure 46kDa bioactive dimer for reproducible results in organoid culture.
- Mouse/rat noggin is a bone morphogenetic protein (BMP) family antagonist used in the culture of intestinal, pancreatic, lung and tumor-derived organoids, maintenance of undifferentiated embryonic stem cells and for stem cell differentiation into neural and microglial lineages.Qkine recombinant mouse noggin protein is a highly pure 46kDa bioactive dimer for reproducible results (animal-free and carrier-protein free).
- Human OSM protein (oncostatin M) is used in the differentiation of human pluripotent stem cells into hepatocyte-like cells. OSM also plays roles in osteogenesis and neurogenesis, and is an important regulator of the hematopoietic stem cell niche in the bone marrow. Qkine human oncostatin M protein is high purity and animal and carrier-protein free for reproducible results.
