Preparation And Storage
Recommended Assay Procedures
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).
Product Notices
- 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.

Companion Products
The A14 monoclonal antibody specifically recognizes the α chain of the Interleukin-5 Receptor (IL-5Rα), which is also known as CD125. IL-5Rα is a 55-60 kDa type I transmembrane glycoprotein that is expressed on B1 B cells, eosinophils, basophils and mast cells. The IL-5Rα chain associates with CD131 (Common β-chain) which serves as the signaling common β-chain subunit of the IL-5R complex as well as for the Interleukin-3 (IL-3R) and GM-CSF receptor (GM-CSFR) complexes. IL-5 promotes the growth and differentiation of eosinophil precursors and activates mature eosinophils. Clone A14 was developed using IL-5Rα-transfected cells as immunogen. This antibody binding can be blocked by IL-5.
The antibody was conjugated to BD Horizon™ BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye has been exclusively developed by BD Biosciences to have minimal spillover into other detectors, making it an optimal choice for multicolor flow cytometry. With an Ex Max at 348 nm and an Em Max at 395 nm, BD Horizon BUV395 can be excited with a 355 nm laser and detected with a 379/28 filter.
