Anti-IL5 Antibody

Primary antibodies targeting Interleukin-5 (IL5) underpin immunology, allergy, and eosinophil-biology research. This rabbit polyclonal IgG reagent from Antibodies.com is supplied unconjugated in a 200 µl format and validated for western blot (WB) and immunohistochemistry (IHC) workflows across human, mouse, and rat samples. IL5 is a Th2-associated cytokine that drives eosinophil production, activation, and survival, and is studied in asthma, allergic inflammation, helminth defense, and eosinophilic disorders. The polyclonal host response supports recognition of multiple epitopes on the IL5 target, which is useful when the protein is expressed at low abundance in tissue sections.

The unconjugated format gives laboratories flexibility to pair the antibody with HRP, biotin, or fluorophore-conjugated secondaries depending on the detection platform. For IHC, the reagent is applied to formalin-fixed, paraffin-embedded tissue or cryosections, while western blot workflows benefit from the antibody's behavior under reducing SDS-PAGE conditions. The product is shipped refrigerated and should be stored in working aliquots to limit freeze-thaw cycles, with the supplied volume supporting multiple experimental runs when partitioned appropriately.
