• Storage conditions:
  Store it under sterile conditions at –20...−80 °C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Endotoxin content:
  <1,0 EU per μg of the protein as determined by the LAL method
• Biological activity:
  Measured by its binding ability in a functional ELISA. Immobilized human ErbB4-His at 10 μg/ml (100 μl/well) can bind biotinylated human NRG1 (Cat:11609 - H01H2), The EC50 of biotinylated human NRG1 (Cat:11609 - H01H2) is 0,4 - 0,92 μg/ml.
