Construction
A DNA sequence encoding the Human NRG1 (Q02297-6) (Thr176-Lys246) was expressed with an N-terminal Met.
Protein Purity
≥ 95% as determined by SDS-PAGE. ≥ 95% as determined by SEC-HPLC.
Molecular Weight8.37 kDa (predicted)
Endotoxin< 10 EU per mg of the protein.
FormulationLyophilized from sterile 30% Acetonitrile, 1/1000 TFA. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.
Reconstitution
Please refer to the lot-specific COA.
Stability & Storage
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
ShippingIn general, Lyophilized powders are shipping with blue ice.
Research Background
Neuregulin 1 or NRG1 is one of four proteins in the neuregulin family that act on the EGFR family of receptors. This growth factor was originally identified as a 44-kD glycoprotein that interacts with the NEU / ERBB2 receptor tyrosine kinase to increase its phosphorylation on tyrosine residues. NRG1 is a trophic factor that has been implicated in neural development, neurotransmission, and synaptic plasticity. NRG1 has multiple isoforms that are generated by the usage of different promoters and alternative splicing of a single gene. Neuregulin 1 (NRG1) is essential for the development and function of multiple organ systems, and its dysregulation has been linked to diseases such as cancer and schizophrenia. NRG1 is a schizophrenia candidate gene and plays an important role in brain development and neural function. Schizophrenia is a complex disorder, with etiology likely due to epistasis.
