Product Info

• Predicted Species Reactivity: Homo sapiens|Human
• Application: Enzyme-linked Immunosorbent assay-Sandwich
• ELISA Kit Detection Method: Colorimetric
• ELISA Kit Duration: 3h
• 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 4 (NRG4). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Neuregulin 4 (NRG4). 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 4 (NRG4), 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 4 (NRG4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 0.156-10ng/mL
• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Neuregulin 4 (NRG4) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Neuregulin 4 (NRG4) were tested on 3 different plates, 8 replicates in each plate.

Target Info

• Gene Symbol: NRG4
• Gene Full Name: neuregulin 4
• Alias Symbols: heregulin 4;HRG4;pro-neuregulin-4, membrane-bound isoform;pro-NRG4.
• NCBI Gene Id: 145957
• Protein Name: Pro-neuregulin-4, membrane-bound isoform
• Description of Target: Low affinity ligand for the ERBB4 tyrosine kinase receptor. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. Does not bind to the ERBB1, ERBB2 and ERBB3 receptors (By similarity).
