Recombinant Human NRG1

• Description:

  Neuregulins are EGF-like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells.

• Gene Name:

  NRG1

• Gene Aliases:

  Acetylcholine receptor-inducing activity, ARIA, Breast cancer cell differentiation factor p45, Glial growth factor, Heregulin, HRG, Neu differentiation factor, Sensory and motor neuron-derived factor
  Recombinant Human Neuregulin-1 Beta (NRG1)

• Gene ID:

  3084

• Accession Number:

  Q02297

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method.

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

• Function:

  The ED(50) was determined by the dose-dependent proliferation of human MCF-7 cells was found to be < 0.3 ng/mL, corresponding to a specific activity of 2.0 x 10^6 Units/mg.

• Molecular Weight:

  7

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

  The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

• Appearance:

  Lyophilized Powder

• Formulation:

  Recombinant Neuregulin-1 was lyophilized from a 0.2 μm filtered 10mM PB, pH 7.0, containing 2% mannitol, 0.5% HSA.

• CAS Number:

  9000-83-3
