BD Pharmingen™ PE-Cy™5 Mouse Anti-Human CD86
Clone IT2.2 (RUO)
Flow cytometric analysis of CD86 expression on Daudi cell line. Daudi cells were stained with either PE-Cy™5 Mouse Anti-Human CD86 (Cat. No. 555666; solid line histogram) or PE-Cy™5 Mouse IgG2b κ Isotype Control (Cat. No. 555744; dashed line histogram). Fluorescent histograms were derived from gated events with the side and forward light-scattering characteristics of viable cells. Flow cytometry was performed on a BD FACScan™ system.

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 PE-Cy5 (formerly known as BD Cy-Chrome™) under optimum conditions, and unconjugated antibody and free PE-Cy5 were removed.
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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
- PE-Cy5 is optimized for use with a single argon ion laser emitting 488-nm light. Because of the broad absorption spectrum of the PE-Cy5 tandem fluorochrome, extra care must be taken when using dual-laser cytometers which may directly excite both PE and Cy5™.
- PE-Cy5 tandem fluorochromes have been reported to bind some classes of human macrophages and granulocytes via Fc receptors, and PE has been reported to bind to mouse B lymphocytes via Fc receptors. Preincubation of mouse leukocytes with Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 can reduce the non-specific binding of PE-Cy5-conjugated reagents to mouse B cells. However, PE-Cy5 conjugated reagents should not be used to stain splenocytes of SJL, NOD, and MRL mice as B lymphocytes and/or other leukocytes have been reported to non-specifically stain regardless of the use of Mouse BD Fc Block™ (the CD72c complex has been implicated for PE-Cy5 binding in these strains). Reagents conjugated to PE, PerCP, PerCP-Cy5.5, APC, and APC-Cy7 tandem fluorochrome can be used on leukocytes from these mouse strains.
- PE-Cy5 is a tandem fluorochrome composed of R-phycoerythrin (PE), which is excited by the 488 nm light of an Argon ion laser and serves as an energy donor, coupled to the cyanine dye Cy5, which acts as an energy acceptor and fluoresces at 670 nm. BD Biosciences Pharmingen has maximized the fluorochrome energy transfer in PE-Cy5, thus maximizing its fluorescence emission intensity, minimizing residual emission from PE, and minimizing lot-to-lot variation.

Antibody Details
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.

Format Details
PE-Cy5
PE-Cy5 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496 nm and 566 nm and an acceptor dye, Cy™5, with an emission maximum (Em Max) at 670-nm. PE designed to be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 670-nm (e.g., a 670/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and Yellow-Green (561-nm) lasers and the acceptor dye can be excited by the Red (627-640-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.
