Regulatory Status Legend
CD11a, clone G-25.2, is derived from hybridization of mouse Sp2/0 myeloma cells with spleen cells from BALB/c mice immunized with human cytotoxic T lymphocytes (CTL).
CD11a (Anti-LFA-1α) recognizes the Mr 180-kdalton (kDa) α chain of the leucocyte function–associated antigen-1 (LFA-1). LFA-1, a member of a subfamily of integrin receptors, is a leucocyte adhesion receptor that binds to an intercellular adhesion molecule (ICAM) on target tissues. This subfamily consists of three heterodimeric proteins that share a common noncovalently-associated β chain (CD18 antigen, Mr 95 kDa) but possess distinct α-subunits recognized by CD11a (anti-LFA-1α), CD11b (Leu-15), and CD11c (Leu-M5).
FITC, fluorescein isothiocyanate, is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties but different spillover characteristics, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly expressed markers whenever possible.

Preparation and Storage
The monoclonal antibody is supplied as 25 µg purified immunoglobulin in 2.0 mL (12.5 µg/mL) of phosphate-buffered saline. The FITC conjugate is supplied as 12.5 µg in 2.0 mL (6.25 µg/mL). Buffered saline contains gelatin and 0.1% sodium azide. The vials should be stored at 2° to 8°C. Conjugated forms should not be frozen and should be protected from prolonged exposure to light. Each reagent is stable for the period shown on the bottle label when stored as directed.
