Anti-IL4 Antibody

For Western blot detection of endogenous interleukin-4 (IL-4), this unconjugated polyclonal antibody from Antibodies.com is raised in rabbits and validated against human, rat, and mouse samples. Interleukin-4 is a Th2-associated cytokine that drives B-cell class switching toward IgE and shapes allergic inflammatory signaling, making it a frequent focus in immunology, asthma, and parasite-infection research. The reagent is supplied at 1 mg/ml in a 100 µl volume, formulated in phosphate buffered saline at approximately pH 7.3 with 0.05% sodium azide added as a preservative. Researchers apply it to cell lysates and tissue extracts across all three reactive species, and aliquoting on arrival is recommended to limit repeated freeze-thaw cycles during long-term storage.
