      APC-R700 Streptavidin
      Flow cytometric analysis of mouse CD45R/B220 or human CD3 expression on leucocytes using Biotin-conjugated primary antibodies and BD Horizon™ APC-R700 Streptavidin. Left Plot - Mouse splenic leucocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with either Biotin Rat IgG2a, κ Isotype Control (Cat. No. 555842; dashed line histogram) or Biotin Rat Anti-Mouse CD45R/B220 antibody (Cat. No. 553085/553086; solid line histogram). The cells were washed and stained with BD Horizon APC-R700 Streptavidin (Cat. No. 565144). The fluorescence histogram showing CD45R/B220 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable leucocytes. Right Plot - Human whole blood was stained with either Biotin Mouse IgG1 κ Isotype Control (Cat. No. 555747; dashed line histogram) or Biotin Mouse Anti-Human CD3 antibody (Cat. No. 555331; solid line histogram). Erythrocytes were lysed with BD PharmLyse™ Lysing Buffer (Cat. No. 555899). The cells were washed and stained with BD Horizon APC-R700 Streptavidin. The fluorescence histogram showing CD3 expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ Cell Analyzer System.

      Recommended Assay Procedures

      BD Horizon™ APC-R700 Streptavidin is a useful second-step reagent for the indirect immunofluorescent staining of cells in combination with biotinylated primary antibodies for flow cytometric analysis.

      BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      2. An isotype control should be used at the same concentration as the antibody of interest.
      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.

      Streptavidin is a non-glycosylated protein that is prepared chromatographically from the bacterium Streptomyces avidinii. Streptavidin homotetramers have a particularly high, non-covalent binding affinity for biotin. When conjugated with fluorochromes, streptavidin has been widely used with biotin-conjugated antibodies and other biotinylated specific-binding molecules (eg, recombinant proteins and lectins) to stain cells and tissues for subsequent multiparameter analysis by flow cytometry, fluorescence microscopy and imaging. Likewise, when conjugated with an enzyme (eg, Horseradish Peroxidase or Alkaline Phosphatase) and coupled with a colorimetric or luminescent substrate development system, streptavidin has found widespread use along with biotinylated antibodies in a number of applications including Western blot, ELISA, ELISPOT, immunocytochemistry and immunohistochemistry.

      Streptavidin was conjugated to BD Horizon APC-R700, which has been developed exclusively by BD Biosciences as a better alternative to Alexa Fluor® 700. APC-R700 excites and emits at similar wavelengths to Alexa Fluor® 700 yet exhibits significantly improved brightness. This dye can be excited by the red laser and detected with the same filter set as Alexa Fluor® (eg, 730/45-nm filter).

      APC-R700
      The BD Horizon™ APC-R700 (APC-R700) Dye is a part of the BD APC red family of dyes. This tandem fluorochrome is comprised of an Allophycocyanin (APC) dye donor that has excitation maximum (Ex Max) of 651-nm and an acceptor dye, R700, with an emission maximum (Em Max) at 706-nm. APC-R700, driven by BD innovation, is designed to be excited by the red (627–640-nm) laser and detected using an optical filter centered near 710-nm (e.g., a 720/40-nm bandpass filter). APC-R700 is a brighter alternative to Alexa Fluor™ 700. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
