IL-13 Monoclonal Antibody (85BRD), APC, eBioscience™, Invitrogen™

Description

• Description: The 85BRD monoclonal antibody reacts with human interleukin-13 (IL-13)
• IL-13, also known as NC30, is a 12.5 kDa protein secreted by activated T helper cells, CD8+ T cells, and NK cells
• The biological activities of IL-13 include suppression of macrophage cytotoxic activity, upregulation of IL-1RA expression and suppression of inflammatory cytokine expression
• Applications Reported: This 85BRD antibody has been reported for use in flow cytometric analysis
• Applications Tested: This 85BRD antibody has been pre-diluted and tested by flow cytometric analysis of stimulated normal human peripheral blood cells using the Intracellular Fixation & Permeabilization Buffer Set (Product # 88-8824-00) and protocol
• Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online
• This may be used at 5 μL (0.5 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and is involved in regulating inflammatory and immune responses
• IL-13 down-regulates macrophage activity, thereby inhibiting the production of pro-inflammatory cytokines and chemokines, and is involved in allergen-induced asthma through mechanisms independent of IgE and eosinophils
• IL-13 also regulates several stages of B cell maturation and differentiation, up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells
• Structurally, IL-13 closely resembles IL-3, IL-4, IL-5 and GM-CSF
• The gene encoding IL-13, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with the IL-13 gene particularly close to IL4.
