Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BB700 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes 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 or 566349).

When setting up compensation, it is recommended to compare spillover values obtained from cells and BD™ CompBeads to ensure that beads will provide sufficiently accurate spillover values.

For optimal results, it is recommended to perform two washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescent staining prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.

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.

Antibody Details

BC4

The BC4 antibody reacts with the high-affinity IgE Fc receptor (FcεRI) expressed in rat mast cells, basophils, and non-B non-T cells. The rat FcεRI is expressed as a tetrameric molecule consisting of one α chain, one β chain, and two identical γ chains. The BC4 antibody has been reported to detect all three chains of the FcεRI by immunoprecipitation. In the rat model, the β chain (FcRβ) is required for cell-surface expression of the complete FcεRI. This differs from the human FcεRI, which can be expressed in trimer (αγ2) or tetramer forms (βγ2). Furthermore, the FcRβ has been characterized as a potent signaling molecule capable of substantially amplifying Fc-mediated cellular responses. The FcεRI functions to mediate cellular degranulation and the release of histamine, leukotrienes, and various cytokines and chemokines. The structure, expression, function, and signaling mechanisms of the FcεRI have been reviewed.

The antibody was conjugated to BD Horizon™ BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40-nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.

BB700

The BD Horizon Brilliant™ Blue 700 (BB700) Dye is part of the BD Horizon Brilliant™ Blue family of dyes. This tandem fluorochrome is comprised of a polymer-technology dye donor with an excitation maximum (Ex Max) of 476-nm and an acceptor dye with an emission maximum (Em Max) at 695-nm. Driven by BD innovation, BB700 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 695-nm (e.g., a 695/20-nm bandpass filter). The donor dye can be excited by the Violet (405 nm) laser and the acceptor dye can be excited by the red (627–640 nm) laser resulting in cross-laser excitation and fluorescence spillover. BB700 Reagents are significantly brighter than equivalent PerCP or PerCP-Cy5.5 reagents and are less sensitive to photobleaching. In addition, BB700 shows much less excitation by the violet (407-nm) laser resulting in less spillover. BB700 has minimal yellow green (562-nm) excitation and is ideal for instruments with both blue (488-nm) and yellow green (562-nm) lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
