Product Description	Recombinant Human NRG1 Beta 1 Protein is expressed from HEK293 with His tag at the N-terminus.It contains Ser177-Glu241.
Product Background	Neuregulin-1 (NRG-1) is a ligand of the epidermal growth factor receptor (erbB), and its interaction involves activation of the glutamatergic N-methyl-Daspartate receptor, which increases the expression of the β2 subunit of the γ- aminobutyric acid receptor and subunits of the nicotinic acetylcholine receptor.
Product Category	Recombinant Protein / Antibody discovery

Protein	NRG1 Beta 1
Synonyms	Pro-NRG1; NRG1; GGF; HGL; HRGA; NDF; SMDF; Beta1; Beta1A
Accession	Q02297-6
Species	Human
Biotinylated	no
Amino Acid Range	Ser177-Glu241
Molecular Weight	The protein has a predicted MW of 8.57 kDa. Due to glycosylation, the protein migrates to 10-13 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human NRG1 Beta 1, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human Her3, hFc Tag with the EC50 of 35.8ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	N-His
Expression System	HEK293
Purity	>95% as determined by Bis-Tris PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22 um filtered solution in 50mM NaAc, 150mM NaCl (pH 5.0). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.； -80°C for 3 months after reconstitution.； Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
