Scientific areas
Qkine manufacture a portfolio of high purity, highly bioactive growth factors for pluripotent stem cell maintenance and differentiation. Qkine proteins are optimized for research areas such as neural differentiation, organoid culture, cellular agriculture and hematopoietic and hepatic research.
Growth factors for organoid research
Qkine is committed to manufacturing enhanced-quality bioactive proteins to improve scientific outcomes and reproducibility in organoid culture.
Reproducible cultures with FGF2-G3
Thermostable FGF2-G3 is a hyperstable form of FGF-2 (bFGF), the essential component for the maintenance of pluripotency in stem cell media.
Growth factors for neural stem cells
High-quality growth factors are essential for developing and maintaining robust, reproducible, and physiologically relevant neural cultures.
Qkine cell therapy grade high purity animal origin-free proteins are manufactured as GMP grade equivalents in an ISO 9001:2015-certified facility, under ISO 20399:2022 standards with GMP compliance and defined quality criteria and documentation.
