Product Overview
This rabbit polyclonal antibody detects interleukin-13 (gene Il13) in rat samples and is validated for ELISA. The predicted molecular weight is 14.1 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.
