RY586 Mouse Anti-Human CD25
RY586 Mouse Anti-Human CD25
Multiparameter flow cytometric analysis of CD25 expression on unstimulated Human leucocytes (Left Plots) and stimulated (Right Plot) Human lymphocytes.    Left Plots- Human whole blood was stained with BD Horizon™ BV421 Mouse Anti-Human CD4 antibody (Cat. No. 562424/562425) and with either BD Horizon™ RY586 Mouse IgG1, κ Isotype Control (Cat. No. 568097; Left Plot) or BD Horizon™ RY586 Mouse Anti-Human CD25 antibody (Cat. No. 568882/568883; Right Plot). 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 intact lymphocytes.    Right Plot - Peripheral blood mononuclear cells (PBMC) were stimulated for 3 days with Phytohemagglutinin (PHA) and then stained with either BD Horizon™ RY586 Mouse IgG1, κ Isotype Control (Cat. No. 568097; dashed line histogram) or BD Horizon™ RY586 Mouse Anti-Human CD25 antibody (Cat. No. 568882/568883; solid line histogram). DAPI (4',6-Diamidino-2-Phenylindole, Dihydrochloride) Solution (Cat. No. 564907) was added to cells right before analysis. The fluorescent histogram showing CD25 expression (or Ig Isotype control staining) was derived from gated events with light-scatter characteristics of viable (DAPI-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 unreacted dye was removed.

推奨アッセイ手順

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® 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 BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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).
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. 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.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  6. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

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.

RY586
The BD Horizon RealYellow™ 586 (RY586) Dye is part of the BD family of yellow-green dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 565-nm and an emission maximum (Em Max) at 586-nm. Driven by BD innovation, RY586 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm Blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY586 can be used as an alternative to PE and we recommend using an optical filter centered near 586-nm (eg, a 586/15-nm bandpass filter). For spectral instruments equipped with a Yellow-Green laser (561-nm), it can be used in conjunction with PE. Compared to PE, RY586 is similar in brightness, minimal spillover into Blue detectors, and increased spillover into the 610/20-nm (PE-CF594) detector. Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
