Questions? Please consult our answers to frequently asked questions at http://www.ebioscience.com/faq. DescriptionThe PC61.5 antibody reacts with mouse CD25, the 55 kDa interleukin-2 receptor α chain (IL-2Rα). CD25 is expressed by early progenitors of the T and B lineage as well as by activated mature T and B lymphocytes. By itself, CD25 binds IL-2 only with low affinity. However, CD25 associates with CD122 (IL-2 receptor beta chain) and CD132 (common γ chain) to form the high affinity IL-2 receptor. Binding of IL-2 to both the high and low affinity classes of IL-2 receptor is inhibited by the PC61.5 antibody. CD25 plays a role in lymphocyte differentiation and activation/proliferation. Applications ReportedFor research use only, not for diagnostic or therapeutic use. This PC61.5 antibody has been reported for use in flow cytometric analysis. The Alexa Fluor® 700 emits at 723 nm and can be excited with the He-Ne 633 laser. Most instruments will require a 685 LP mirror and 710/20 filter. Please make sure that your instrument is capable of detecting this fluorochome. Applications TestedThis PC61.5 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.25 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. References
