Multiparameter flow cytometric analysis of HLA-DR expression on Human peripheral blood leucocyte populations. Whole blood was stained with either BD Horizon™ RY586 Mouse IgG2a, κ Isotype Control (Cat. No. 568131; Left Plot) or BD Horizon™ RY586 Mouse Anti-Human HLA-DR antibody (Cat. No. 568153/568154; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). The bivariate pseudocolor density plot showing the correlated expression of HLA-DR (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the forward and side light-scatter characteristics of viable leucocyte populations. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 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.
Recommended Assay Procedures
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
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- 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.

Antibody Details
G46-6
The G46-6 monoclonal antibody specifically binds to HLA-DR, a major histocompatibility complex (MHC) class II antigen. HLA-DR antigens are encoded by genes within the Human Leukocyte Antigen (HLA) Complex located on chromosome 6. HLA-DR is a transmembrane heterodimeric glycoprotein composed of an α chain (36 kDa) and a β subunit (27 kDa) expressed primarily on antigen presenting cells: B cells, dendritic cells, monocytes, macrophages, and thymic epithelial cells. HLA-DR is also expressed on activated T cells. This molecule plays a major role in mediating cellular interactions during antigen presentation to CD4-positive T cells.

Format Details
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.
