- Recombinant bovine HGF protein is a potent, high-purity NK1 isoform of bovine hepatocyte growth factor (HGF). Bovine HGF differs from human HGF at several key amino acid residues that are predicted to affect bioactivity and receptor binding. Use of species-specific HGF growth factor will facilitate media optimization for cellular agriculture (cultivated meat) and veterinary applications. Also available is Qk061 Porcine HGF (NK1). The highly scalable animal-free manufacture and enhanced bioactivity make this suitable for chemically-defined media and reproducible scale-up.20kDa naturally occurring isoform of HGF, animal-free and carrier-protein free.
- Recombinant bovine/porcine FGF2 protein 145 aa (bFGF/basic FGF) for the development of species-specific bovine (cow) and porcine (pig) cellular agriculture protocols and veterinary research applications. Used in comparative cell culture media optimization studies alongside Qk056, the 154aa form of porcine/bovine FGF-2.FGF-2 is used extensively in the maintenance and proliferation of induced pluripotent (iPSC) and embryonic stem cells (ESC)1-3 and for enhancement of proliferation in primary cell culture.High purity 16 kDa FGF-2 / bFGF protein, animal origin-free (AOF) and carrier-protein free (CF).
- Recombinant bovine/porcine FGF2 protein 154 aa (bFGF/basic FGF), this is the long form of FGF-2 used for the development of optimized serum-free culture media for species-specific bovine (cow) and porcine (pig) cultivated meat and veterinary research applications. Used in comparative media optimization studies with Qk040 porcine/bovine FGF-2 145 aa.FGF-2 is used extensively in the maintenance and proliferation of induced pluripotent (iPSC) and embryonic stem cells (ESC)1-3 and for enhancement of proliferation in primary cell culture.High purity 16 kDa FGF-2 / bFGF 154 aa protein, animal origin free (AOF) and carrier-protein free (CF).
- FGF2-G3 (145 aa) protein is a thermostable engineered form of FGF-2 (bFGF). Qk052 comprises the 145 aa form of FGF-2 (Qk025) with the nine amino acid substitutions developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3 145 aa).FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. This new 145 aa thermostable FGF-2 protein allows direct comparison of efficacy in systems using FGF-2 145 aa (Qk025) for chemically defined stem cell and organoid culture media, and cultured meat media development.High purity 16 kDa bioactive FGF2-G3 145 aa protein. Animal-free (AOF), carrier protein-free and with no His-tag.
- Recombinant FGF2-G3 (FGF2-STAB®) protein is a thermostable engineered form of FGF-2 (bFGF). Qk053 is the 154 aa mature domain of FGF-2 (Qk027) with nine amino acid substitutions to enhance stability without impacting bioactivity developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3).Recombinant FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. FGF2-G3 also has applications in chemically defined stem cell and organoid culture media, and cultured meat media development.High purity 17 kDa bioactive FGF2-G3 protein. Animal-free (AOF), carrier protein-free and with no His-tag.
- Neurotrophin 3 protein is part of the neurotrophin family and plays a crucial role in embryonic development and the maintenance and neuroprotection of the adult nervous system.NT-3 protein is used in cell culture to promote the differentiation and survival of specific neural subpopulations in both the central nervous system and peripheral nervous system such as sensory neurons, cortical neurons, and oligodendrocytes. It is also involved in the maintenance of endothelial cells and myocardial cells.Recombinant Neurotrophin 3 protein is a non-covalently linked homodimer with a molecular weight of 27.3 kDa.Qkine NT3 protein is animal-free (AOF), carrier-free, tag-free, and non-glycosylated to ensure its purity with exceptional lot-to-lot consistency. It is suitable for the culture of reproducible and high-quality cortical neurons and oligodendrocytes.
