Anti-IL-3Rβ Antibody

Raised in rabbit and supplied by Antibodies.com as an affinity-purified polyclonal reagent, this primary antibody targets the IL-3Rβ subunit (also known as CD131, CSF2RB or the common β chain shared by the GM-CSF, IL-3 and IL-5 receptors). It is provided as a 50 µl liquid format at approximately 1 mg/ml in phosphate-buffered saline (PBS) containing 0.05% sodium azide at roughly pH 7.2, and the IgG preparation is unconjugated, making it suitable for use with standard secondary-detection workflows. Validation data on the supplier page list Western blot (WB) as the primary application, with reactivity confirmed against human, mouse and rat samples. The immunogen is a synthetic peptide corresponding to an internal region of human IL-3Rβ, and the antibody is purified from rabbit serum by antigen-affinity chromatography using the immunizing peptide, giving a polyclonal reagent of high specificity for research use only. For short-term storage the vial should be kept refrigerated at 2–8 °C, while long-term storage is recommended at –20 °C in small aliquots to limit freeze-thaw cycles. This product from Antibodies.com is intended for laboratory research applications such as Western blotting of cell and tissue lysates to investigate IL-3Rβ expression and signalling.
