Product Overview
This rabbit polyclonal antibody recognizes interleukin-13 (gene IL13) in human samples and is validated for ELISA and Western blot. The predicted molecular weight is 15.8 kDa, and the supplier reports an observed band at about 37 kDa.
Interleukin-13 (IL-13) is a type 2 cytokine produced by Th2 cells, group 2 innate lymphoid cells and mast cells. It signals mainly through the IL-4Rα/IL13RA1 receptor and STAT6, driving mucus production, airway hyperresponsiveness and tissue remodeling, and it is a central mediator in allergic inflammation, asthma and anti-parasite immunity.
