Anti-IL-4 Antibody

Manufactured by Antibodies.com, this affinity-purified Rabbit polyclonal antibody is raised against Interleukin-4 (IL-4) and is supplied as a 50 µl liquid at 1 mg/ml in phosphate-buffered saline (PBS) containing0.05% sodium azide at approximately pH 7.2. The reagent is unconjugated and validated for Western Blot (WB) applications, with an estimated purity greater than 95%. It is recommended for research use only and cross-reacts with Human, Mouse and Rat samples, making it a versatile choice for cytokine studies across the most common laboratory species. Affinity purification ensures low background, while the polyclonal format offers the advantage of recognizing multiple epitopes on the IL-4 target for robust detection in western blotting workflows. Store the vial refrigerated (typically 2–8 °C) to preserve activity, and avoid repeated freeze–thaw cycles; the sodium azide in the buffer serves as a microbial preservative for liquid handling at the bench. Suitable for use in immunology, inflammation and cell-signalling research, this anti-IL-4 reagent provides consistent, lot-validated performance for detecting endogenous IL-4 protein levels in cell lysates and tissue extracts.
