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 MP4-25D2 recognizes human IL-4.

Background

IL-4 is a 15-19 kD pleiotropic immune cytokine secreted by activated TH2 cells. It has many biological roles, including the regulation in humoral and adaptive immunity, the inhibition of bone resorption, the stimulation of activated B-cell and T-cell proliferation, and initiation of allergic responses. Moreover, IL-4 induces a positive feedback loop by stimulating differentiation of naive helper T cells, or Th0 cells, to Th2 cells which in turn secrete more IL-4. Increased IL-4 production and overproduction of IL-4R are found in many cancers. IL-4 has a significant effect on tumor progression by increasing apoptosis resistance via tumor growth enhancement. IL-4 may also play a part in the immune dysregulation that occurs in most HIV-1 infected patients.
