RB705 Mouse Anti-Human CD86 (B7-2)
RB705 Mouse Anti-Human CD86 (B7-2)

Multiparameter flow cytometric analysis of CD86 (B7-2) expression on Human peripheral blood leukocyte populations. Fresh whole blood was first treated with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899) to lyse erythrocytes. After washing, the leukocytes were preincubated with BD Pharmingen™ Human BD Fc Block™ (Cat. No. 564219) and then stained with either BD Horizon™ RB705 Mouse IgG2b, κ Isotype Control (Cat. No. 570273; Left Plot) or BD Horizon™ RB705 Mouse Anti-Human CD86 (B7-2) antibody (Cat. No. 570615/570703; Right Plot). The bivariate pseudocolor density plot showing the correlated expression of CD86 (B7-2) [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 leukocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software.

Preparation And Storage

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. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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

  1. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
  2. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  3. 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).
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
  6. 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.
  7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  8. 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.

IT2.2

The IT2.2 monoclonal antibody specifically binds to CD86. CD86 is a ~ 75 kDa type I transmembrane glycoprotein which is also known as B7-2 or B70. CD86 is primarily expressed on monocytes, dendritic cells, Langerhans cells, and activated B cells including B lymphoid cells in germinal centers and Epstein-Barr virus transformed B-cell lines. CD86 is a ligand for CD28 and CD152 (CTLA-4) and may play an important role in costimulation of T cells in primary immune responses. Competitive binding assays demonstrate that, while both the IT2.2 and FUN-1 monoclonal antibodies recognize the same CD86 molecule, they react with different epitopes. IT2.2 blocks the costimulation activity of CD86 in functional studies and blocks binding of human CTLA-4-Ig fusion protein to CD86 gene-transfected cells.

RB705
The BD Horizon RealBlue™ 705 (RB705) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 707-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB705 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB705 can be used as an alternative to PerCP-Cy5.5 or BB700 and we recommend using an optical filter centered near 710-nm (e.g., a 695/40 or 710/50-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PerCP-Cy5.5. RB705 is on average brighter than PerCP-Cy5.5 and BB700, and has minimal spillover into Yellow-Green detectors.
