Genbank #: Q02297
a.a: 177–237
Background: Neuregulins (NDF, heregulin, GGF ARIA, or SMDF) are EGF-like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells.
UniProt Q02297
Synonym(s): NRG1B, NRG-1beta, Neuregulin 1, MSTP131, HGL, Glial Growth Factor, GGF1, Heregulin, Alpha, NDF, Neu Differentiation FactorHRG
Purity: ≥96% by SDS-PAGE and HPLC
Endotoxin Level: <0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity: The ED50 was determined by the dose-dependent proliferation of human MCF-7 cells was found to be <0.3ng/ml, corresponding to a specific activity of 2x 106 Units/mg.
Formulation: Lyophilized from a 0.2 µm filtered 10 mM phosphate buffer, pH 7.0, containing 2% mannitol, 0.5% HSA.
Format: lyophilized protein
Reconstitution: Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability: The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles. Reference(s): 1.
