• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Neuregulin 1 (NRG1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Neuregulin 1 (NRG1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Neuregulin 1 (NRG1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Neuregulin 1 (NRG1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Neuregulin 1 (NRG1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Neuregulin 1 (NRG1) were tested on 3 different plates, 8 replicates in each plate.

Target Info

• Gene Symbol: Nrg1
• Gene Full Name: neuregulin 1
• Alias Symbols: glial growth factor;neuregulin 1 type III beta 3;pro-neuregulin-1, membrane-bound isoform;pro-NRG1.
• NCBI Gene Id: 112400
• Protein Name: Pro-neuregulin-1, membrane-bound isoform
• Description of Target: 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. The multiple isoforms perform diverse functions such as inducing growth and differentiation of epithelial, glial, neuronal, and skeletal muscle cells; inducing expression of acetylcholine receptor in synaptic vesicles during the formation of the neuromuscular junction; stimulating lobuloalveolar budding and milk production in the mammary gland and inducing differentiation of mammary tumor cells; stimulating Schwann cell proliferation; implication in the development of the myocardium such as trabeculation of the developing heart. Binds to ERBB4 and ERBB3. Acts as a ligand for integrins and binds (via EGF domain) to integrins ITGAV:ITGB3 or ITGA6:ITGB4. Its binding to integrins and subsequent ternary complex formation with integrins and ERRB3 are essential for NRG1-ERBB signaling (By similarity). Induces the phosphorylation and activation of MAPK3/ERK1, MAPK1/ERK2 and AKT1, and ligand-dependent ERBB4 endocytosis is essential for the NRG1-mediated activation of these kinases in neurons (PubMed:17250808).
