Two-color analysis of the expression of Vα 8.3 TCR on peripheral lymphocytes. C57BL/6 lymph node cells were incubated simultaneously with FITC-conjugated B21.14, PE-conjugated anti-mouse CD4 RM4-5 (Cat. No. 553048/553049), and PE-conjugated anti-mouse CD8a 53-6.7 (Cat. No. 553032/553033) monoclonal antibodies. Flow cytometry was performed on a BD FACScan™ flow cytometry system.

Regulatory Statusの凡例
Any use of products other than the permitted use without the express written authorization of Becton, Dickinson and Company is strictly prohibited.
Preparation and Storage
推奨アッセイ手順
For flow cytometry of cell suspensions from peripheral lymphoid tissues, it is recommended that multicolor staining be performed to distinguish T lymphocytes from non-T cells.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- 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 B21.14 monoclonal antibody specifically recognizes some members of the Vα 8 T-cell Receptor (TCR) subfamily of mice having the a, b, c, and d haplotypes of the Tcra gene complex (e.g., all strains tested). It recognizes an epitope in the CDR1 of Vα 8.3, but not Vα 8.2, TCR subfamily member, as does the KT50 mAb (Cat. No. 557096, for the biotinylated antibody). Site-directed mutagenesis has identified three amino acids which are necessary for antibody reactivity and which are unique to Vα 8.3 among the five functional Vα 8 TCR subfamily members. On a common H-2K[k] background and using the KT50 mAb, the frequency of Vα 8.3 TCR-bearing T lymphocytes has been demonstrated to be higher in Tcra[a/a] mice than in Tcra[a/b] mice. Furthermore, studies of congenic strains suggest that CD8+ Vα 8.3 TCR-bearing T lymphocytes undergo negative selection in mice expressing MHC class I antigens of the H-2[d] haplotype.
