Bulk anti-IL-4 In Vivo Antibody – Low Endotoxin (11B11)
ichorbio’s anti-IL-4 In Vivo Antibody – Low Endotoxin (11B11) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.

Anti-IL-4 In Vivo Antibody – Low Endotoxin (11B11) recognizes an epitope on Mouse IL-4
This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
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.

ELISA Capture, ELISPOT, Flow Cytometry, Neutralization, Immunoprecipitation, Functional Assays, CyTOF, Immunohistochemistry
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.
