Preparation and Storage
推奨アッセイ手順
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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- 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.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
- 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.
