Description of Human Heregulin alpha / Neuregulin-1

Recombinant Human Neuregulin-1/Heregulin Alpha (EGF Domain) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 65 amino acids and having a total molecular mass of 7.4kDa. NRG1-A is purified by proprietary chromatographic techniques.

 

Biological Activity

The ED50 was determined by the dose-dependent stimulation of the proliferation of human MCF-7 cells is less than 40 ng/ml, corresponding to a specific activity of > 2.5104 units/mg.

 

Reconstitution

It is recommended to reconstitute the lyophilized NRG1-A in sterile 18M-cm H2O not less than 100g/ml, which can then be further diluted to other aqueous solutions.

 

Stability

Lyophilized NRG1-A although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution NRG1-A should be stored at 4C between 2-7 days and for future use below -18C. Please avoid repeated freeze-thaw cycles.
