Mouse ERFE (Erythroferrone) ELISA Kit

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 Mouse ERFE. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse ERFE. 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 Mouse ERFE, 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 Mouse ERFE in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Iron-regulatory hormone that acts as an erythroid regulator after hemorrhage: produced by erythroblasts following blood loss and mediates suppression of hepcidin (HAMP) expression in the liver, thereby promoting increased iron absorption and mobilization from stores (PubMed:24880340, PubMed:30097509, PubMed:31800957, PubMed:34002695). Promotes lipid uptake into adipocytes and hepatocytes via transcriptional up-regulation of genes involved in fatty acid uptake (PubMed:22351773). Inhibits apoptosis and inflammatory response in cardiomyocytes via promotion of sphingosine-1-phosphate (S1P) and cAMP-dependent activation of AKT signaling (PubMed:30566056). Inhibits autophagy induced by nutrient deficiency in hepatocytes via promoting the phosphorylation of IRS1, AKT, and MTOR, and thereby subsequent activation of the AKT-MTOR signaling pathway (PubMed:24187137). Negatively regulates the differentiation of osteoblasts, potentially via sequestering BMP2, and thereby inhibits the activation of SMAD signaling (PubMed:34002695). The reduction in BMP2 signaling in osteoblasts also results in an increase in expression of the osteoclastogenesis-promoting factors TNFSF11/RANKL and SOST, thereby indirectly promotes bone resorption (PubMed:34002695) [The Uniprot Consortium]
