Antibody DetailsProduct DetailsReactive Species Human Host Species Goat Immunogen Sf 21-Derived Recombinant Human Interleukin-21 Receptor subunit Extracellular Domain 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_2830738 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-21 R. A suggested method would be to stain cells expressing IL-21 R with 2.5 µg/106 cells in a total staining volume of 100 µl followed by PN:G641. Western Blotting: To detect Human IL-21 R 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-21 R is 2 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. Additional Applications Reported In Literature ? 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-21 Receptor (IL-21 R) recognizes Human IL-21 R. 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 A novel cytokine related to IL-2 and IL-15 was recently identified and designated IL-21 . The receptor for IL-21 (IL-21R, also termed NILR for novel Interleukin receptor) is a new member of the class I cytokine receptor family.1,2 IL-21R forms a complex with the common cytokine receptor g chain, gc, and mediates IL-21 signaling.3,4 Both IL-21R and the gc are necessary for the IL-21 function. IL-21 and its receptor activate JAK-STAT signaling pathway. IL-21R is expressed in spleen, thymus, natural killer (NK), T and B cell lines. IL-21 plays a role in the proliferation and maturation of NK, B and T cell populations. PubMed NCBI Gene Bank ID UniProt.org References & CitationsTechnical ProtocolsCertificate of Analysis |
