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 BUV737 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 (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

  1. This antibody was developed for use in flow cytometry.
  2. 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.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.

G7-26

The G7-26 monoclonal antibody specifically recognizes the constant region of human Immunoglobulin E (IgE). It does not crossreact with other immunoglobulin heavy chain isotypes. IgE exists in a transmembrane form that is expressed by B lymphocytes and serves as an antigen receptor. Soluble IgE is produced and secreted by activated B cells and plasma cells. IgE may bind through its constant region to cell surface receptors, such as the high-affinity (FcεRI) or low-affinity (FcεRII/CD23) receptors for IgE. FcεRI is expressed on mast cells, basophils, and at lower levels, on dendritic cells and monocytes. FcεRII/CD23 is expressed by B cells and by some other cell types including T cells, monocytes, eosinophils, neutrophils, follicular dendritic cells, and Langerhans cells. Crosslinking of Fc receptor-bound IgE antibodies by multivalent antigens or allergens can induce phagocytosis or the cellular release of inflammatory mediators. Although IgE can provide immune protection against pathogenic parasites, it may also play a central role in a variety of allergic disorders.

The antibody was conjugated to BD Horizon™ BUV737 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 737-nm. BD Horizon Brilliant BUV737 can be excited by the ultraviolet laser (355 nm) and detected with a 740/35 filter.  Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover into channels detecting Alexa Fluor® 700-like dyes (eg, 712/20-nm filter).

Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BUV737 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended. Different BUV737 reagents (eg, CD4 vs. CD45) can have slightly different fluorescence spillover therefore, it may also be necessary to use clone specific compensation controls when using these reagents.

BUV737
The BD Horizon Brilliant™ Ultraviolet 737 (BUV737) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 735-nm. BUV737, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 740-nm (e.g., 740/35 bandpass filter). The acceptor dye can be excited by the Red (628–640nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
