Regulatory Status Legend
The G-25.2 monoclonal antibody specifically recognizes CD11a which is also known as Leukocyte function-associated molecule 1 alpha chain (LFA-1A or LFA-1α). CD11a is a ~180 kDa type I transmembrane glycoprotein that is encoded by ITGAL (Integrin subunit alpha L) that belongs to integrin α-chain family. CD11a is a leucocyte adhesion receptor that noncovalently complexes with CD18 to form the LFA-1 heterodimer (CD11a/CD18) which binds to intercellular adhesion molecules (ICAMs) expressed on target tissues including ICAM-1 (CD54), ICAM-2 (CD102), ICAM-3 (CD50), ICAM-4, or ICAM-5. The CD11a antigen is expressed on virtually all normal peripheral blood leucocytes. It is essential for many immune responses that require cell-to-cell contact, such as lymphocyte adhesion, natural killer (NK) and T-lymphocyte cytolysis, and T lymphocyte proliferation. Activation of lymphocytes through the T-cell antigen receptor (TCR) upregulates LFA-1 function, converting the antigen to a high-avidity state. Expression of LFA-1 on monocytes is upregulated by γ-interferon (IFN-γ). While normal cells possess both the α and β LFA-1 chains, cells of subjects with some leukemias, lymphomas, or leucocyte adhesion deficiency (LAD) may lack the entire LFA-1 molecule or the α or β chain. The absence of LFA-1 on tumor cells may provide a mechanism for their escape from immune surveillance.
The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm. BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor® 700-like dyes (eg, 712/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor® 700 and PerCP-Cy5.5 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
BV711 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 711 nm. This dye offers a very bright choice for the violet laser. Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor® 700 and PerCP-Cy5.5 detectors. BV711 will also have moderate spillover into the BD Horizon Brilliant™ Violet 786 detector.

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 BV711 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).
