Precision
Intra-assay Precision (Precision within an assay): CV%<8%        
Three samples of known concentration were tested twenty times on one plate to assess.    
Inter-assay Precision (Precision between assays): CV%<10%        
Three samples of known concentration were tested in twenty assays to assess.      
               
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of human NRG2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. May also promote the heterodimerization with the EGF receptor.
Gene References into Functions
  1. reduced expression of NRG2 led to marginal increase in cell survival under arsenite-induced stress. PMID: 27345716
  2. examination of the effect of isoforms on angiogenesis PMID: 14722120
  3. Nrg-2-induced Acetylcholine Receptor transcription requires an N-box motif and is regulated by alternative splicing. PMID: 15961242
  4. Linkage interval for GLC1M was refined to a smaller region. The NRG2 gene was excluded as the causative gene for juvenile-onset primary open angle glaucoma. PMID: 17563728
  5. Gln43 of NRG2beta is both necessary and sufficient for NRG2 stimulation of ErbB4 coupling to IL3 independence. PMID: 17945187
  6. NRG2 was positive in almost all breast cancers studied. High expression is related to the biological aggressiveness of breast cancer. PMID: 17962208
