Anti-IL4 Antibody

Raised in rabbit and affinity-purified for reliable detection of the IL-4 cytokine, this unconjugated polyclonal reagent from Antibodies.com is supplied as a 50 µl liquid at 1 mg/ml in phosphate-buffered saline (PBS, approximately pH 7.3) containing 0.05% sodium azide as a preservative. The antibody is of the IgG isotype, validated for Western blot (WB) application, and has been shown to react with Human, Mouse, and Rat samples, making it suitable for cross-species studies of Th2-associated cytokine signalling. For best stability, the manufacturer recommends shipping on cold packs and storing aliquots at -20 °C, avoiding repeated freeze/thaw cycles. The reagent is intended for research use only and pairs well with standard anti-rabbit IgG secondary reagents for chemiluminescent or colorimetric WB detection of endogenous IL-4 protein.
