      Preparation And Storage

      1. For in vitro diagnostic use.

      2. When stored at 2° to 8°C, the antibody reagent is stable until the expiration date shown on the label. Do not use after the expiration date.

      3. The antibody reagent should not be frozen or exposed to direct light during storage or during incubation with cells. Keep the reagent vial dry.

      4. Alteration in the appearance of the reagent, such as precipitation or discoloration, indicates instability or deterioration. In such cases, the reagent should not be used.

      5. The antibody reagent contains sodium azide as a preservative; however, care should be taken to avoid microbial contamination, which may cause erroneous results.

      Becton Dickinson Immunocytometry Systems (BDIS) CD19 (Leu™-12) phycoerythrin (PE) is a single-color direct immunofluorescence reagent for the enumeration of B lymphocytes (CD19+) in peripheral blood using fluorescence microscopy or flow cytometers such as the FACSCalibur™, FACSort™, FACScan™, or FACS Analyzer™.

      PE
      R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is 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 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
