CD122, PerCP-eFluor™ 710, clone: TU27, eBioscience™

Description

Description: This TU27 monoclonal antibody reacts with human CD122, which is also known as interleukin-2 receptor beta (IL-2R beta). This receptor is expressed on NK cells, activated T cells, some B cells, monocytes, and T cell leukemias. CD122 can also be detected during early NK cell commitment. IL-2R beta associates with the IL-2R alpha (CD25) or IL-15R alpha and common gamma chain (CD132) to form the high affinity IL-2 and IL-15 receptors, respectively. By itself, this membrane receptor can bind IL-2, but with intermediate affinity. The binding of IL-2 results in internalization of the cytokine, tyrosine phosphorylation of IL-2Rbeta, and activation of signaling cascades such as the JAK/STAT pathway.Applications Reported: This TU27 antibody has been reported for use in flow cytometric analysis.Applications Tested: This TU27 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. PerCP-eFluor™ 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome.Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 μL of cell sample + 100 μL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.Excitation: 488 nm; Emission: 710 nm; Laser: Blue Laser.Filtration: 0.2μm post-manufacturing filtered.
