Revvity Human Interleukin 4 (IL4), also known as B Cell Stimulatory Factor 1, is an anti-inflammatory glycoprotein of 129 amino acids. It is produced by a variety of cells including Th2, mast cells, and basophils. Via binding to type 1 IL4 receptor, IL4 acts on hematopoietic cells and promotes class switching to IgE. A high level of IL4 has been associated with an increased production of IgE and allergy. This cytokine suppresses IFN-? and IL-8 production. It inhibits the production of inflammatory cytokines (IL1, IL6, and TNFa). In vivo, injection of IL4 has been shown to protect against experimental arthritis and immune complex-induced lung inflammation in rats. It could potentially be used in the treatment of chronic inflammatory diseases. IL4 may also play a role in the pathogenesis of chronic lymphocytic leukemia. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)

Revvity AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)
