Description
The JOVI.1 monoclonal antibody recognizes an epitope common to a large proportion of human CD4+ or CD8+ T lymphocytes that express the T cell receptor beta chain (TCRβ). The antibody was generated from a mouse immunized with transgenic mouse lymphoid cells that expressed the rearranged human Vβ3-Cβ1 TCR chain derived from the cloned human HA1.7 T helper cell. This antibody reacts with TCR-Cβ1+ T cells and one of several different TCRβ V regions, but not with TCR-Cβ2+ T cells. JOV1.1 antibody reportedly recognized several Cβ1 TCR expressing cell lines or clones including Jurkat, CH7C17, and HA1.7 cells. The JOVI.1 antibody can be used to stimulate proliferative responses by JOVI.1-positive T cells. It can also reportedly be used for immunoprecipitation and to stain JOVI.1+ T cells in frozen tissue sections.
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 to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
3. 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.
4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
5. An isotype control should be used at the same concentration as the antibody of interest.
6. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
7. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
8. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

9. Researchers should determine the optimal concentration of this reagent for their individual applications.
10. 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.
