BV480 Rat Anti-Mouse CD25
BV480 Rat Anti-Mouse CD25
Two-color flow cytometric analysis of CD25 expression on mouse splenocytes. Mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with APC Rat Anti-Mouse CD4 antibody (Cat. No. 553051/561091) and either BD Horizon™ BV480 Rat IgG1, λ Isotype Control (Cat. No. 566128; Left Plot) or BD Horizon BV480 Rat Anti-Mouse CD25 antibody (Cat. No. 566202/566120; Right Plot). Two-color flow cytometric dot plots showing the correlated expression of CD25 (or Ig Isotype control staining) versus CD4 were derived from gated events with the forward and side light-scatter characteristics of viable splenocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System.
BV480 Rat Anti-Mouse CD25
Flow cytometric analysis of CD25 expression on activated mouse splenocytes. Mouse splenic leucocytes were stimulated for 3 days with concanavalin A (ConA). The cells were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody and then stained with and either BD Horizon BV480 Rat IgG1, λ Isotype Control (dashed line histogram) or BD Horizon BV480 Rat Anti-Mouse CD25 antibody (solid line histogram). The fluorescence histogram showing CD25 expression (or Ig Isotype control staining) was derived from events with the forward and side light-scatter characteristics of viable lymphoblasts.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV480 under optimum conditions, and unconjugated antibody and free BD Horizon BV480 were removed.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

PC61

The PC61 monoclonal antibody specifically binds to CD25, the low-affinity IL-2 Receptor α chain (IL-2Rα, p55) expressed on activated T and B lymphocytes from all mouse strains tested. IL-2Rα by itself is not a signaling receptor. However, it can combine with IL-2 Receptor β (CD122) and γc (CD132) chains to form high-affinity, signaling receptor complexes for IL-2. Resting T and B lymphocytes and resting and activated NK cells do not express IL-2Rα. CD25 is transiently expressed at a low level during normal B-cell development in the bone marrow on the CD45R/B220low TdT- sIg- Pre-B/Pre-B-II and CD45R/B220low TdT- sIgM+ sIgD- immature B stages, but not on the CD45R/B220low TdT+ sIg- Pro-B/Pre-B-I stage nor on CD45R/B220high TdT- sIgM+ sIgD+ mature B cells. It is expressed at a higher level during a very early stage of T-cell development in fetal and adult thymus. Peripheral CD25+CD4+ lymphocytes called regulatory T (Treg) cells are involved in the maintenance of self-tolerance. It has also been reported that dendritic cells express CD25, recognized by mAb 7D4. The PC61 antibody recognizes an epitope of CD25 which is distinct from the IL-2 binding site and from those recognized by mAbs 3C7 and 7D4. It blocks binding of IL-2 to CD25, presumably by inducing a conformational change in CD25.

BV480
The BD Horizon Brilliant Violet™ 480 (BV480) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology fluorochrome has an excitation maximum (Ex Max) of 440-nm and an emission maximum (Em Max) of 479-nm. Driven by BD innovation, BV480 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 480-nm (e.g., a 525/50 bandpass filter). The increased fluorescence intensity of BV480 and narrower emission spectra, make it a good alternative for BV510 or V500. Due to its excitation profile, BV480 will also has less cross-laser excitation with the UV laser, resulting in less spillover into UV channels compared to BV510. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
