Clone SAM.2.rMAb (also known as KFN) (RUO)
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).

- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

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.
