Biological Activity
The ED50 is <1 ng/mL as measured by MCF-7 cells, corresponding to a specific activity of >1 × 106 units/mg.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against PBS.

Endotoxin Level
<0.2 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human Heregulin-1 beta1 (rHuHeregulin-1 β1) to 100 µg/mL using ddH2O.

Storage & Stability
Lyophilized recombinant Human Heregulin-1 beta1 (rHuHeregulin-1 β1) is stored at -20°C. After reconstitution, it is stable at 4°C for 2 weeks or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

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[1].
