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.

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.

Description

Specificity

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 basophils^{1, 2}. IL-4 signaling through the IL-4 receptor alpha chain (IL-4Ra) induces the differentiation of naive T cells to Th2 cells^{3, 4} and stimulates B cell differentiation, proliferation, and class switching to IgG1 and IgE isotypes⁵. In addition, IL-4 is implicated in normal wound healing^{6, 7} and airway inflammation in patients with asthma⁸.
