Neuregulin-1 signals through ErbB3/ErbB4 receptor tyrosine kinases to regulate neuronal survival, myelination, and synaptic plasticity, making it a critical tool for neuroscience and cancer biology research. This tag-free recombinant human NRG1 fragment (177–237 aa of Isoform 12) encompasses the EGF-like domain responsible for receptor binding, and its potent bioactivity is confirmed by an ED50 of less than 50 ng/mL in serum-free MCF-7 cell proliferation assays, corresponding to a specific activity exceeding 2.0 × 10⁴ IU/mg. The E. coli expression system yields a non-glycosylated protein that provides a suitable basis for receptor-ligand binding studies via SPR or ELISA, neuronal and stem cell differentiation experiments, and cell survival assays where defined, glycosylation-independent signaling is preferred. Purity above 96% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for sensitive cell-based and in vivo tumor biology models.
