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.

The AER-37 (CRA-1) monoclonal antibody specifically recognizes FcεRIα which is also known as the high affinity immunoglobulin epsilon receptor subunit alpha (Fc-epsilon RI-alpha). FcεRIα is a type I transmembrane glycoprotein that is encoded by FCER1A (Fc fragment of IgE receptor Ia) which belongs to the Ig gene superfamily. FcεRIα serves as the binding subunit for the Fc region of IgE. It forms part of a heterotetrameric, high-affinity IgE Fc receptor (FceR1/FcεR1) that includes signal transducing subunits, one β-chain (FcεRIβ encoded by MS4A2) and two disulfide-linked γ-subunits (FcεRIγ encoded by FCER1G). FcεRIα is normally expressed on basophils and mast cells and can also be expressed on some monocytes, Langerhans cells, dendritic cells, and eosinophils from allergic donors. FcεRIα plays a major role in allergic responses and in the presentation of allergens to the immune system. The AER-37 antibody reportedly does not compete with IgE for FceR1 binding.
The antibody was conjugated to BD Horizon™ BV786 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 786-nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
