Anti-Mouse IL-4 (Clone 11B11) – Purified in vivo GOLD™ Functional Grade
Pricing & Details
Antibody DetailsProduct DetailsReactivity Species Mouse Host Species Rat Immunogen Partially Purified Native Mouse IL-4 Product Concentration ≥ 5.0 mg/ml Endotoxin Level < 1.0 EU/mg as determined by the LAL method Purity ≥95% monomer by analytical SEC ⋅ >95% by SDS Page Formulation This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration. Product Preparation Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates. Storage and Handling Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

See directions on lot specific datasheets, as information may periodically change. DescriptionSpecificity Clone 11B11 recognizes an epitope on mouse IL-4. Antigen Distribution IL-4 is secreted by Th2 cells, NKT cells, mast cells, eosinophils, and basophils. Background IL-4 antibody, 11B11, recognizes mouse IL-4, also known as B-cell differentiation factor (BCDF) and B-cell stimulatory factor (BSF1). IL-4 is a pleiotropic 20 kDa cytokine secreted by T helper 2 cells (Th2) cells, natural killer T (NKT) cells, mast cells, eosinophils, and basophils1,2. IL-4 signaling through the IL-4 receptor alpha chain (IL-4Ra) induces the differentiation of naive T cells to Th2 cells3,4 and stimulates B cell differentiation, proliferation, and class switching to IgG1 and IgE isotypes5. In addition, IL-4 is implicated in normal wound healing6,7 and airway inflammation in patients with asthma8.
