This antibody is specific for swine IL-13 protein. A BLAST analysis was used to suggest reactivity with IL-13 from swine sources based on 100% homology with the immunizing sequence. The following homologies may indicate chances of cross-reactivity when amino acid similarity and not just exact sequence is accounted: 89-90% homology to IL-13 from sheep, dolphin, beluga, and bovine, 83-88% to human and certain monkey IL-13, 80-82% to dusky titi, macaque, baboon, mangabey, dog, llama, camel, and galago, 75-78% to horse, and 67-72% to rat, mouse, and gerbil. Cross-reactivity with IL-13 from other sources has not been determined.

Target Information

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.
