- Dickkopf-related protein 1 (DKK-1) is a key player in the Wnt signaling pathway and regulates embryonic development, tissue balance, and diseases, including cancer. DKK-1 is a member of the DKK protein family and acts as a potent Wnt pathway antagonist.In cell culture, DKK1 is pivotal for controlling cell fate, self-renewal, and differentiation by inhibiting the canonical Wnt/β-catenin pathway through LRP5/6 co-receptors. DKK-1 has been widely used in various applications including guiding stem cell differentiation, particularly in neural and osteogenic pathways, and mimicking dysregulated Wnt signaling seen in cancers. Its inhibitory role is also crucial for anterior development.Human DKK-1 has a molecular weight of 25.7 kDa. This protein is carrier-free and tag-free to ensure its purity with exceptional lot-to-lot consistency. DKK1 is suitable for the culture of reproducible and high-quality stem cells and other relevant cells.
- 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 active mature human epidermal growth factor. Our recombinant EGF protein is manufactured to the highest purity in E. coli and extensively tested, making it ideal for use in chemically defined iPSC, ESC and organoid culture media.
- Porcine EGF is an essential growth factor belonging to the Epidermal Growth Factor family that stimulates the proliferation and differentiation of cells. It is used for the differentiation of induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) towards epithelial, neural, mesoderm and hematopoietic lineages. Porcine-EGF is becoming rapidly adopted as a species-specific growth factor in the cultivated meat sector. Porcine EGF is also an essential component of many organoid media supporting the culture and differentiation of a wide variety of organoids including intestine and liver organoids.Porcine EGF has a molecular weight of 6.3 kDA. This protein is animal-free, carrier protein-free, His-tag-free and non-glycosylated to ensure a pure recombinant protein with exceptional lot-to-lot consistency.
- Human FGF2 /bFGF protein (145 aa) is our gold-standard and recommended FGF2 / bFGF protein for induced pluripotent stem cell (iPSC) and embryonic stem cells (ESC) maintenance, and induced pluripotent and mesenchymal stem cells proliferation and differentiation.High purity and bioactivity 17 kDa FGF2 / bFGF protein, animal-derived component free (ACDF) and carrier-protein free (CF) comprising the core structured region (145 amino acids) sufficient for full biological activity.
- Recombinant human FGF2 protein (154 aa) is a highly bioactive, long–form of human fibroblast growth factor 2 protein. FGF-2 protein is used to support the maintenance of human embryonic stem cells and proliferation and differentiation of induced pluripotent and mesenchymal stem cells. This 154 aa form of FGF-2 comprises the core structured region and N-terminal extension.High purity and bioactivity 17 kDa FGF-2 / bFGF protein, animal-free (AOF) and carrier-protein free (CF).
- 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).
