CytoGrow™ Recombinant NRG1-β1 (Bovine/Porcine), E. coli, Tag Free
Recombinant neuregulin-1 beta 1 produced in E. coli for consistent and cost-effective production while maintaining strong biological activity. Supplied in a tag-free format, this protein preserves its native functional domains, enabling reliable performance across a range of cell-based applications.
NRG1-β1 is a member of the epidermal growth factor (EGF) family and plays a critical role in cell signaling through ErbB receptor activation. It is involved in regulating cell proliferation, differentiation, and survival, particularly in neuronal, cardiac, and epithelial cell systems.
This recombinant NRG1-β1 is widely used in cell culture to support neuronal development, Schwann cell function, and cardiomyocyte maturation. It is also commonly applied in neuroscience research, regenerative medicine, cancer biology, and organoid models.
