Description: The polyclonal 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: The biotinylated anti-human IL-13 polyclonal antibody has been reported for use in ELISA and ELISPOT.
Applications Tested: The biotinylated anti-human IL-13 polyclonal antibody has been tested as the detection antibody in a sandwich ELISA for analysis of human IL-13 in combination with the purified PVM13-1 (14-7139) antibody for capture and recombinant human IL-13 (14-8139) as the standard. A suitable range of concentrations of this antibody for ELISA detection is 0.5-2 µg/mL. A standard curve consisting of doubling dilutions of the recombinant cytokine standard over the range of 1000 pg/mL - 8 pg/mL should be included in each ELISA plate.
Filtration: 0.2 µm post-manufacturing filtered.
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.
