Immunogen
Purified Recombinant Mouse IL-4 (Accession # P07750)
Formulation
This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Storage and Handling
The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted biotin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Applications and Recommended Usage?
Quality Tested by Leinco
Western Blotting: To detect Mouse IL-4 this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as PN:A106 and a chromogenic substrate such as PN:T343. The detection limit for Mouse IL-4 is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-207.
ELISA Sandwich Assay: This antibody can be used as the detection antibody in a sandwich ELISA at a concentration of approximately 0.1-0.4 µg/ml when used in conjunction with PN:I-662 as the capture antibody at 2-8 µg/ml and an optimal second step reagent such as PN:A106 for the detection of Mouse IL-4.
Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.

Description

Specificity
Goat Anti-Mouse Interleukin-4 (IL-4) recognizes Mouse IL-4. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
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.
