LIFR, also known as CD118(Cluster of Differentiation 118), is a subunit of a receptor for leukemia inhibitory factor. This gene encodes a protein that belongs to the type I cytokine receptor family. It is mapped to 5p31.1. The LIF receptor(LIFR) is the low-affinity binding chain that, together with the high-affinity converter subunit gp130, forms a high-affinity receptor complex that mediates the action of the leukemia-inhibitory factor. LIF is a polyfunctional cytokine that affects the differentiation, survival, and proliferation of a wide variety of cells in the adult and the embryo. Mutations in this gene cause Schwartz-Jampel syndrome type 2, a disease belonging to the group of the bent-bone dysplasias. A translocation that involves the promoter of this gene, togerther with the pleiomorphic adenoma gene 1, is associated with salivary gland pleiomorphic adenoma, a common type of benign epithelial tumor of the salivary gland. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA) Intended Use: For quantitative detection of human LIFR in cell culture supernates, serum and plasma (heparin, EDTA). Sensitivity: <10pg/ml Range: 156-10,000pg/ml Specificity: Natural and recombinant human LIFR Test Principle: This human LIFR BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for LIFR has been precoated onto 96-well plates. Standards(NSO) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for LIFR is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human LIFR amount of sample captured in plate. Kit Components: 96-well plate precoated with human LIFR antibody, 1 Lyophilized recombinant human LIFR standard, 10ng/tube*2 Biotinylated human LIFR antibody, 130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 130ul (dilution 1:100) Sample diluent buffer, 30ml Antibody diluent buffer, 12ml ABC diluent buffer, 12ml TMB color developing agent, 10ml TMB stop solution, 10ml Storage and Stability: Store powder at 4C liquid at -20C.
