RY610 Mouse Anti-Human TCR Cβ2
RY610 Mouse Anti-Human TCR Cβ2
Multiparameter flow cytometric analysis of TCR Cβ2 expression on Human peripheral blood lymphocytes.  Human whole blood was stained with BD OptiBuild™ RB545 Mouse Anti-Human TCR Cβ1 antibody (Cat. No. 756564) and with either BD Horizon™ RY610 Mouse IgG1, κ Isotype Control (Cat. No. 571151; Left Plot) or BD Horizon™ RY610 Mouse Anti-Human TCR Cβ2 antibody (Cat. No. 571687/571760; Right Plot) at 1 µg/test. Erythrocytes were lysed with BD FACS Lysing™ Solution (Cat. No. 349202). The bivariate pseudocolor density plot showing the correlated expression of TCR Cβ2 (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals was derived from gated events with the light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 SE Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

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.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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.
  3. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  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. 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. For more information visit https://www.bdbiosciences.com/en-us/support/product-notices.
  8. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

SAM.2.rMAb

The SAM.2.rMAb is a recombinant monoclonal antibody that recognizes TCR Cβ2 expressed by a large proportion of CD4+ and CD8+ T cells. Thymocytes and mature peripheral T cells predominantly express a heterodimeric T cell receptor (TCR αβ) for antigen which is comprised of disulfide-liked transmembrane α and β chain subunits. The constant region of the TCR α subunit is encoded by TRAC, whereas the TCR β subunit is encoded by either of two highly homologous constant region genes, TCRB1 for TCR Cβ1 or TCRB2 for TCR Cβ2. The JOVI.1 antibody alternatively recognizes TCR Cβ1 expressed by the other TCR αβ+ T cells. These antibodies are effectively used together in multicolor staining and flow cytometric analyses to identify and characterize the natures of either TCR Cβ1+ or TCR Cβ2+ T cells in heterogeneous cell populations.

Note - Some human CD3- and TCR-specific antibodies might not be compatible to co-stain human T cells with SAM2.rMab. To confirm compatibility and immunofluorescent staining protocols, please visit: https://www.bdbiosciences.com/content/dam/bdb/marketing-documents/discover-learn/thought-leadership/events/POSTER-AAI%20202024-S-Riguad.pdf

RY610
The BD Horizon RealYellow™ 610 (RY610) Dye is part of the BD® family of yellow-green dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 557-nm and an emission maximum (Em Max) at 610-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RY610 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY610 can be used as an alternative to PE-CF594 and we recommend using an optical filter centered near 610-nm (eg, a 610/20-nm bandpass filter). For spectral instruments equipped with a Yellow-Green laser (561-nm), it can be used in conjunction with PE-CF594.
