Recombinant Human Pro-neuregulin-1, membrane-bound isoform (NRG1), partial (Active)

1Measured by its binding ability in a functional ELISA. Immobilized NRG1 at 2 μg/ml can bind human ERBB3, the EC50 is 18.24-23.66 ng/ml. 2The ED50 as determined by the dose-dependent stimulation of the proliferation of MCF-7 cells is 2.626-7.598 ng/mL.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
