Ser 2 - Lys 246

A DNA sequence encoding the N-terminal fragment (Ser 2-Lys 246) of human NRG1 isoform beta1 (Q02297-6) was expressed, fused with the Fc region of mouse IgG1 at the N-terminus.

> 88 % as determined by SDS-PAGE

1. Measured by its ability to bind with human ErbB4-His (Cat:503994) in a functional ELISA.
2. Measured by its ability to bind with human ErbB3-His (Cat:503568) in a functional ELISA.

The recombinant human NRG1/mFc is a disulfide-linked homodimer. The reduced monomer comprises 481 amino acids and has a predicted molecular mass of 53.4 kDa. The apparent molecular mass of the monomer is approximately 67 kDa in SDS-PAGE under reducing conditions due to glycosylation.

Pro-neuregulin-1, membrane-bound isoform

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 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. 

Lyophilized from sterile PBS, pH 7.4
1. 5 % trehalose and mannitol are added as protectants before lyophilization.

< 1.0 EU per μg of the protein as determined by the LAL method

Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
