Biological Activity
Description
HRG1-β1 belongs to a family of structurally-related polypeptide growth factors derived from alternatively spliced genes, induces Fn14 expression in MCF7 cells. NRG1-beta 1 Protein, Human (CHO) is the recombinant human-derived NRG1-beta 1 protein, expressed by CHO , with tag free.
Background
HRG1-β1 activates HER2/HER3 signaling and up-regulate Fn14 gene expression in parental MCF7 cells. HRG1-β1-mediated Fn14 up-regulation in MCF7/HER2-18 cells is required for maximal MMP-9 production.
Verified Bioactivity
ED50 ≤ 0.5 ng/mL, determined by the dose-dependent stimulation of the proliferation of human MCF-7 cells.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of PBS.
<0.2 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
