Regulatory Status Legend
The L272 monoclonal antibody specifically recognizes CD26 which is also known as Dipeptidyl peptidase IV (DPP IV), a serine protease. CD26 is a ~120 kDa type II transmembrane glycoprotein that is encoded by DPP4 and belongs to the DPP4 activity and/or structure homologue (DASH) protein family. It is associated with the binding of the TAT transactivating protein of the HIV. CD26 and CD45 act in a costimulatory fashion on T lymphocytes. Present on peripheral blood T lymphocytes, the CD26 antigen is upregulated on phytohemagglutinin (PHA) and concanavalin A (Con A)-stimulated peripheral blood mononuclear cells (PBMCs). The CD26 antigen is found on approximately 50% of CD4 and approximately 30% of CD8 cells. It is also found on some mature thymocytes, B cells, natural killer (NK) cells, monocytes, macrophages, epithelial cells, EBV transformed B-cell lines, and hairy cell leukemia. Absolute numbers of CD4+CD26+ and CD8+CD26+ cells are reported to be lower in HIV-positive individuals. The CD26-CD4+ cell appears to be a reservoir for HIV. CD26 bright CD4 lymphocytes are CD25+ and CD45RO+ memory T lymphocytes.
The antibody was conjugated to BD Horizon™ BUV805 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348 nm and an acceptor dye with an Em Max at 805 nm. BD Horizon Brilliant BUV805 can be excited by the ultraviolet laser (355 nm) and detected with a 820/60 filter and a 770LP.
BUV805 is a tandem fluorochrome that combines BD Horizon BUV395 and an acceptor dye with an Em Max at 805 nm. BUV805 has been exclusively developed by BD Biosciences for instruments equipped with a 355-nm UV laser.

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 BD Horizon BUV805 under optimal conditions that minimize unconjugated dye and antibody.
- This antibody was developed for use in flow cytometry.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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 optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794).
