NRG1 Protein QC Testing

純度: > 85 % as determined by SDS-PAGE SDS-PAGE
生物活性:
Measured in a serum-free cell proliferation assay using MCF-7 human breast cancer cells. Karey, K.P. et al. (1988) Cancer Research 48:4083.
The ED50 for this effect is typically 20-60 ng/mL.
內**: < 1.0 EU per μg of the protein as determined by the LAL method
穩定性: Samples are stable for up to twelve months from date of receipt at -70℃
預測N端: Ser 2
分子量: 
The recombinant human NRG1  comprises 245 amino acids and has a predicted molecular mass of 26.8 kDa. The apparent molecular mass of the monomer is approximately 48 kDa in SDS-PAGE under reducing conditions due to glycosylation.
緩沖液: Lyophilized from sterile PBS, pH7.4.
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.

NRG1 Protein Usage Guide

儲存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

NRG1蛋白背景綜述

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.
