Anti-IL-5 Antibody

From Antibodies.com, this Rabbit polyclonal reagent is raised against human Interleukin-5 (IL-5) and is validated specifically for Western blot (WB) applications, with a recommended working dilution of 1:500–1:1,000. The immunogen corresponds to a recombinant fusion protein spanning amino acids 20–134 of human IL-5 (NP_000870.1), and the antibody is affinity-purified to deliver consistent specificity. Supplied as a 50 µl liquid formulation at 1 mg/mL in phosphate-buffered saline (PBS, approximately pH 7.2) containing 0.05% sodium azide as a preservative, it is unconjugated and of the IgG isotype, allowing straightforward pairing with secondary detection reagents. The reagent cross-reacts with Human, Mouse and Rat samples, making it suitable for comparative studies across these species, and the predicted molecular weight of the target is approximately 18–23 kDa. The product is shipped at 4 °C on cold packs and should be aliquoted and stored at –20 °C upon arrival, with repeated freeze/thaw cycles avoided to preserve antibody integrity. Intended for research use only, this primary antibody is part of the Antibodies.com Primary Antibodies catalog and is offered through the AFMS distribution channel.
