Anti-Mouse IL-4 In Vivo Antibody - Ultra Low Endotoxin (11B11)

Ultra-Low Endotoxin, anti-mouse

Rat IgG1 Kappa

Interleukin-4 (IL-4) is a pleiotropic immune cytokine secreted by activated TH2 cells that inhibits bone resorption. IL-4 is critical for inducing allergic responses. It has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It is also a key regulator in humoral and adaptive immunity. IL-4 is required for the pathogenesis of atopic diseases and immune regulation.

We use the IMPACT test generated by IDEXX Laboratories to guarantee our Ultra Low Endotoxin antibodies are pathogen free. Our rat antibodies are tested for: - Mycoplasma spp - Mycoplasma pulmonis - Pneumonia virus of mice - Kilham's rat virus - Toolan's H1 virus - Rat parvovirus - Lymphocytic choriomeningitis virus - Rat cytomegalovirus - Sendai virus - Rat coronavirus - Sialodacryoadenitis virus - Rat minute virus - Seoul virus - Mouse adenovirus - Reovirus 3 - Rat theilovirus

ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 0.5-2.0 µg/ml. - ELISPOT Capture: This Low Endotoxin Functional Formulation antibody has been reported for use as the capture antibody in a sandwich ELISPOT assay. Aseptically coat plates at a concentration of 2-6 µg/ml is recommended. - Neutralization: Anti-Mouse IL-4 (clone 11B11) antibody can neutralize the bioactivity of natural or recombinant IL-4. The Low Endotoxin Functional Formulation purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for neutralization of mouse IL-4 bioactivity in vivo. - Each investigator should determine their own optimal working dilution for specific applications.
