CD25 Monoclonal Antibody (P4A10), eFluor™ 660, eBioscience™, Invitrogen™

Description

Description: This P4A10 monoclonal antibody reacts with canine CD25, the 55 kDa interleukin-2 receptor alpha (IL-2Ralpha) chain. As in humans and mice, CD25 in dogs is expressed by early T and B lineage progenitors as well as by activated mature T and B lymphocytes. CD25 associates with the IL-2R beta (CD122) and gamma (CD132) chains to form the high-affinity IL-2 receptor. On its own, CD25 binds IL-2 with low affinity. Along with CD4 and Foxp3, CD25 is a major marker used to define regulatory T cells. The P4A10 antibody has been reported to recognize the same epitope as the anti-human CD25 monoclonal antibody ACT-1, but with greater affinity. Applications Reported: This P4A10 antibody has been reported for use in flow cytometric analysis. Applications Tested: This P4A10 antibody has been pre-titrated and tested by flow cytometric analysis of normal canine peripheral blood lymphocytes. This can be used at 5 μL (0.125 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. eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered.
