IL-13 Monoclonal Antibody (eBio13A), eBioscience™, Invitrogen™

Description

• Description: The eBio13A antibody reacts with mouse IL-13
• IL-13 is a cytokine produced mainly by Th2 cells, but also by antigen-primed CD8 T cells
• IL-13 has a strong involvement in allergic inflammation and parasitic clearing and in cancer models has been shown to have either inhibitory or stimulatory activity depending on the tumor
• In humans, IL-13 is found to play a role in isotype switching in B cells
• IL-13 is implicating in down modulating macrophage activity, through the reduction of pro-inflammatory cytokines (IL-1, IL-6, IL-8, IL-10, IL-12) Applications Reported: The eBio13A antibody has been reported useful for ELISA and ELISPOT capture, as well as intracellular staining for flow cytometric analysis
• Applications Tested: The eBio13A antibody has been tested as the capture antibody in a sandwich ELISA (and ELISPOT) for analysis of mouse IL-13, in combination with the biotinylated eBio1316H antibody for detection (13-7135) and recombit mouse IL-13 (14-8131) as the standard
• A suitable range of concentrations of this antibody for ELISA capture is 1.0 - 4.0 μg/mL
• A standard curve consisting of doubling dilutions of the recombit standard over the range of 1000 pg/mL - 8.0 pg/mL should be included in each ELISA plate
• The Functional Grade Purified eBio1316H antibody (16-7135) is recommended for in vitro blocking studies
• Purity: Greater than 90%, as determined by SDS-PAGE
• Aggregation: Less than 10%, as determined by HPLC
• 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.
