Recombinant human VEGF 165
Human vascular endothelial growth factor 165 (VEGF 165) is used in culturing primary vascular endothelial cells (like HUVEC and HMVEC) and promoting the proliferation and differentiation of iPSC-derived endothelial cells. Vasculature in various types of organoid models relies on the efficiency of recombinant human VEGF-165 protein. It regulates mesenchymal stem cell differentiation and helps in maintaining hematopoietic stem cells and tumor cells in culture.
Key features of Qkine VEGF 165:
• Higher bioactivity than an alternative supplier
• High purity 38 kDa homodimer
• Suitable for chemically-defined media
• Carrier-protein free
• Animal-free (ADCF)
• Cost-effective

Recombinant human Shh
Human Sonic hedgehog (Shh), with its diverse functions, is used to enhance the specification of hPSCs towards a dopaminergic fate and has a significant role in generating hPSC-derived GABAergic medium spiny neurons, motor neurons, serotonergic neurons, midbrain organoids, and ventral forebrain organoids.
Key features of Qkine Shh:
• Highly pure and bioactive 19.8 kDa N-terminal fragment (C24II)
• Suitable for chemically-defined media
• Carrier-protein free
• Animal-free
• Cost-effective

“Our lab has been using FGF2 and activin A from Qkine in stem cell cultures for many months now. Our epiblast stem cells and trophoblast stem cells never looked better. Qkine has provided us with exceptional customer service and most importantly top-quality, affordable growth factors. We will be definitely using their products in the future.”
Recombinant human activin A PLUS, Qk005, and recombinant zebrafish Fgf2, Qk002, feature in the recent publication:
