GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.≥95%(SDS-PAGE)See COA

Mecanismos bioquímicos y fisiológicos
Neuregulin 1 or NRG1 is one of four proteins in the neuregulin family that act on the EGFR family of receptors. This growth factor was originally identified as a 44-kD glycoprotein that interacts with the NEU / ERBB2 receptor tyrosine kinase to increase i

Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein (rp222178) - Protein Bioactivity
Measured in a serum-free cell proliferation assay using MCF‑7 human breast cancer cells. The ED50 for this effect is 0.01 ng/mL.
Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein (rp222178) - SDS-PAGE
3 μg/lane of Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 7.0 kDa under reducing conditions and 10.6 & 15.5 kDa under non-reducing conditions.
The NRG1-beta 2/HRG1-beta 2 is a class of EGF-like signaling molecules. Its domain is rich in cysteine residues and disulfide bonds, potentially facilitating disulfide bond formation (Uniprot ID: Q02297-7).
