BD Horizon™ BV605 Mouse Anti-Human CD25
Clone BC96 (RUO)
Flow cytometric analysis of CD25 expression on unstimulated (Left Plots) and activated (Right Plot) human lymphocytes.
Left Plots: Whole blood was stained with APC Mouse Anti-Human CD4 antibody (Cat. No. 555349/561840/561841) and with either BD Horizon™ BV605 Mouse IgG1, κ Isotype Control (Cat. No. 562652) or BD Horizon™ BV605 Mouse Anti-Human CD25 antibody (Cat. No. 567571/567572) as indicated. The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plot showing the correlated expression of CD25 (or Ig Isotype control staining) versus CD4 was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes.
Right Plot: Peripheral blood mononuclear cells were stimulated for 3 days with Phytohemagglutinin (PHA) and then stained with either BD Horizon™ BV605 Mouse IgG1, κ Isotype Control (dashed line histogram) or BD Horizon™ BV605 Mouse Anti-Human CD25 antibody (solid line histogram). BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. The fluorescence histogram showing CD25 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable (7AAD-negative) lymphoblasts.
Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

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 to the dye under optimum conditions and unconjugated antibody and free dye were removed.
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and CompBead to ensure that BD® CompBeads are appropriate for your specific cellular application.
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).
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- CF™ is a trademark of Biotium, Inc.
- Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from BD Horizon™ BV421 may be observed. Therefore, we recommend that individual compensation controls be performed for every BD Horizon™ BV605 conjugate.

Antibody Details
BC96
The BC96 monoclonal antibody specifically binds to human CD25, the low-affinity alpha subunit of the Interleukin-2 Receptor (IL-2Rα), which is also known as TAC antigen. IL2RA encodes CD25 which is a 55 kDa type I transmembrane glycoprotein comprised of an extracellular region with two Complement Control Protein domains (CCP) followed by a transmembrane region and a short cytoplasmic tail. CD25 is constitutively expressed at high levels on natural T regulatory cells and variably expressed on conventional T cells and B cells and their precursors, NK cells, monocytes, and macrophages. CD25 expression can be highly upregulated upon antigenic or mitogenic stimulation of T cells or B cells. A soluble form of CD25 is found in biological fluids due to proteolytic cleavage of the extracellular region of transmembrane CD25. CD25 noncovalently associates with CD122 (IL-2Rβ chain) and CD132 (IL-2Rγ, also known as the common γ chain or γc) to form the high-affinity signal-transducing IL-2R complex (IL-2Rαβγ). This heterotrimeric receptor mediates biological activities of IL-2 which can act as a cellular activation, growth, and differentiation factor and regulator of cell viability. Analysis of CD25 expression can be used to characterize the nature of normal leucocytes in their resting states or activated during inflammatory or immune responses as well as those present in certain disease states.
This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon™ BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon™ BV605 is a tandem fluorochrome of BD Horizon™ BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon™ PE-CF594 detectors off the green or yellow-green lasers. BD Horizon™ BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.

Format Details
BV605
The BD Horizon Brilliant Violet™ 605 (BV605) dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 407-nm and an acceptor dye with an emission maximum (Em Max) at 605-nm. BV605, driven by BD innovation, is designed to be excited by the Violet laser (405-nm) and detected using an optical filter centered near 610-nm (e.g., a 610/20-nm bandpass filter). The acceptor dye can be excited by the Yellow-Green (561-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
