Human/mouse/rat activin A protein is a member of the TGFβ superfamily of growth factors used for maintenance of pluripotency in many induced pluripotent stem cell (iPSC) and embryonic stem cell (ESC) lines, and to...
Qkine
Zebrafish FGF-2 protein (bFGF/basic FGF) has been used extensively to support the maintenance and proliferation of human induced pluripotent (iPSC) and embryonic stem cells (ESC), used in the original Ludwig et al...
Qkine
Human/rat/porcine/bovine FGF-10 protein promotes lung organoid formation and induces branching morphology. FGF-10 protein is used widely in organoid culture, embryonic stem cell (ESC) and induced-pluripotent stem...
Qkine
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...
Qkine
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...
Qkine
Human R-spondin 1 protein (RSP1) 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....
Qkine
Human BMP2 protein (bone morphogenetic protein 2) protein is member of the TGFβ family and a key regulator of embryogenesis and potent differentiation factor of embryonic stem cells (ESC) and induced pluripotent stem...
Qkine
Recombinant human TGF-β1 PLUS protein is the first entirely animal-free recombinant human transforming growth factor beta 1 (TGFβ1) protein for highly reproducible results and compatible with chemically-defined stem...
Qkine
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...
Qkine
Recombinant human HGF (NK1) protein is a potent, high purity NK1 isoform of human hepatocyte growth factor (HGF) that promotes efficient differentiation of human iPSCs to hepatocyte-like cells at just 10 ng/ml with...
Qkine
Human 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...
Qkine
Recombinant human GDF-15 (growth differentiation factor 15) protein is a member of the TGFβ family and subject of intense interest as a marker of cellular stress and for its role in metabolism, cancer and pregnancy....
Qkine
Mouse LIF (murine leukemia inhibitory factor) protein supports the derivation, propagation and expansion of mouse embryonic stem cells (ESC), and maintenance of pluripotency. LIF protein increases the robustness of...
Qkine
Human FGF-2 /bFGF protein (145 aa) is our gold-standard and recommended FGF-2 / bFGF protein for induced pluripotent stem cell (iPSC) and embryonic stem cells (ESC) maintenance, and induced pluripotent and mesenchymal...
Qkine
Human FGF-2 / bFGF protein (154 aa) is a highly bioactive, long–form of human fibroblast growth factor 2 protein. Human bFGF / FGF-2 protein is used to support the maintenance of human embryonic stem cells and...
