Preparation and Storage

The monoclonal antibody is supplied as 50 µg purified immunoglobulin in 2.0 mL (25 µg/mL) of phosphate-buffered saline. The FITC conjugate is supplied as 50 µg in 2.0 mL (25 µg/mL). Buffered saline contains gelatin and 0.1% sodium azide. The vials should be stored at 2º to 8ºC. 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.

The Anti-BrdU antibody, clone B44, is derived from hybridization of Sp2/0-Ag14 mouse myeloma cells with spleen cells from BALB/c mice immunized with iodouridine-conjugated ovalbumin.

Bromodeoxyuridine (BrdU) is a uridine derivative that can be incorporated specifically into DNA in place of thymidine. Anti-BrdU identifies BrdU (but not thymidine) in single-stranded DNA, free BrdU, or BrdU coupled to a protein carrier. The antibody also reacts with iodouridine. DNase-I cleaves each strand of DNA at random and permits the binding of Anti-BrdU antibody to its antigen (BrdU).

Fluorescein (FITC) is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 518-nm. FITC is designed to be excited by the Blue laser (488-nm) and detected using an optical filter centered near 520 nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
