Antibody DetailsProduct DetailsReactive Species Human Host Species Goat Immunogen Purified Recombinant Human IL-15 Rα (>98%) Endotoxin Level <0.1 EU/µg as determined by the LAL method Formulation This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present. State of Matter Lyophilized Storage and Handling The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months. Country of Origin USA Shipping Next Day Ambient RRIDAB_2830735 Applications and Recommended Usage? Quality Tested by Leinco Flow Cytometry: It is recommended to use the indirect method for signal enhancement when enumerating cells expressing IL-15 Rα. A suggested method would be to stain cells expressing IL-15 Rα with 2.5 µg per 1 x 106 cells in a total staining volume of µl followed by PN:G641. Western Blotting: To detect Human IL-15 Rα this polyclonal antibody can be used at a concentration of 0.1-0.2 µg/ml. This polyclonal antibody should be used in conjunction with compatible second-step reagents such as PN:G505 and a chromogenic substrate such as PN:T343. The detection limit for Human IL-15 Rα is 1 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is PN:I-549. Additional Applications Reported In Literature ? IHC (NBF/Par.): This antibody should give satisfactory staining results when used at a concentration of 15 µg/ml. The recommended secondary antibody for IHC is PN:G505. For chromogenic detection with high signal and low background use PN:D100 or PN:K107. Neutralization: This antibody is useful for neutralization of Human IL-15 Rα bioactivity. The antibody dose required to neutralize 50% (ND50) of the biological activity of Human IL-15 Rα (at 0.03 µg/ml of IL-15 sRα and 2.0 ng/ml of IL-15) is 1-4 µg/ml. Immunocytochemistry: Suitable for use at concentration of 1-15 µg/mL. CyTOF-ready: Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation. Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change. DescriptionDescriptionSpecificity Goat Anti-Human Interleukin-15 Receptor Alpha (IL-15 Rα) recognizes Human IL-15 Rα. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research. Background Interleukin 15 receptor, alpha subunit is a subunit of the interleukin 15 receptor. IL15RA is a cytokine receptor that specifically binds IL15 with high affinity. The receptors of IL15 and IL2 share two subunits, the IL2R beta and IL2R gamma chains. This forms the basis of many overlapping biological activities of IL15 and IL2. IL15RA is structurally related to IL2R alpha, but is capable of binding IL15 with high affinity independent of other subunits, which suggests the distinct roles between IL15 and IL2. This receptor is reported to enhance cell proliferation and expression of apoptosis inhibitor BCL2L1/BCL2-XL and BCL2.
