Preparation And Storage
Recommended Assay Procedures
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Note: When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed. For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).
Product Notices
- 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 F2.67 monoclonal antibody specifically recognizes the variable gamma 7 region of the γ subunit of the mouse γδ T cell receptor for antigen, TCR Vγ7 (using the Heilig and Tonegawa nomenclature for mouse TCR γ and δ chains). TCR Vγ7 is encoded by the Trgv7 (T cell receptor gamma, variable 7) gene element. TCR Vγ7 is expressed by a subset of TCR γδ+ thymocytes in the late fetal and adult thymus and by γδ T cells in peripheral lymphoid tissues. TCR Vγ7+ γδ T cells predominate in intestinal epithelial tissue which contains a large proportion of these γδ T cells derived from extrathymic generation. Proteins encoded by Btnl1 (butyrophilin-like 1) and Btnl6 (butyrophilin-like 6) are expressed by intestinal epithelial cells. These butyrophilin-like molecules can reportedly shape the TCR-dependent development and function of TCR Vg7+ γδ T cells within the gut. TCR Vγ7+ γδ T cells help maintain the integrity of the intestinal mucosa guarding against cellular stress or damage caused by inflammation, transformation, or infection. The F2.67 antibody is useful for TCR Vγ7+ thymocyte and γδ T cell separations and analyzing TCR Vγ repertoires expressed by thymocytes, peripheral T cells, and T cell hybridomas in developmental and other experimental model systems.
