Human Interleukin-4 Receptor Alpha ELISA Kit

This Human Interleukin-4 Receptor Alpha ELISA Kit from Innovative Research is intended for quantitative detection of human IL4R in cell culture supernates, serum and plasma (heparin, EDTA, citrate). Strip well format. Reagents for up to 96 tests.

This human IL4R ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IL4R has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: M26-H232) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IL4R is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB are used to visualize HRP enzymatic reaction. TMB is 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 IL4R amount of sample captured in plate.

Additional Information: The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: The interleukin 4 receptor is a type I cytokine receptor. IL4R is its human gene. It is mapped to 16p12.1. This gene encodes the alpha chain of the interleukin-4 receptor, a type I transmembrane protein that can bind interleukin 4 and interleukin 13 to regulate IgE production. The encoded protein also can bind interleukin 4 to promote differentiation of Th2 cells. A soluble form of the encoded protein can be produced by proteolysis of the membrane-bound protein, and this soluble form can inhibit IL4-mediated cell proliferation and IL5 upregulation by T-cells. Allelic variations in this gene have been associated with atopy, a condition that can manifest itself as allergic rhinitis, sinusitus, asthma, or eczema. Polymorphisms in this gene are also associated with resistance to human immunodeficiency virus type-1 infection. Alternate splicing results in multiple transcript variants. ; Immunogen sequence: 369
