APC Mouse Anti-Human TCR βF1
APC Mouse Anti-Human TCR βF1

Multicolor flow cytometric analysis of TCR βF1 expression by human peripheral blood lymphocytes. Whole blood was surface stained with FITC Mouse Anti-Human TCR αβ (Cat. No. 555547; Top Plots) and PE Mouse Anti-Human TCR γδ (Cat. No. 561994; Bottom Plots) antibodies. Erythrocytes were lysed and leucocytes were fixed with 1x BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049). After permeabilization with BD™ Phosflow Perm Buffer I (Cat. No. 557885), the cells were then stained with either APC Mouse IgG1, κ Isotype Control (Cat. No. 554681; Left Plots) or APC Mouse Anti-Human TCR βF1 antibody (Cat. No. 566052; Right Plots). Two color contour plots showing the correlated expression of TCR βF1 (or Ig Isotype control staining) versus TCR αβ or TCR γδ were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

Preparation And Storage

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 APC under optimum conditions, and unconjugated antibody and free APC were removed.

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  5. This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

8A3 (βF1)

The 8A3 monoclonal antibody is also known as the β Framework 1 (βF1) antibody. After treatment of lymphoid cells with permeabilization reagents, this antibody recognizes a common epitope on the β chain of the T Cell Receptor (TCR) for antigen which is expressed by thymocytes and peripheral T lymphocytes. It does not react with γδ TCR-bearing T cells. The 8A3 antibody does not stain the surface of living cells. This suggests that the TCR β constant region epitope recognized by the 8A3 antibody is normally hidden on viable cells.

APC
Allophycocyanin (APC), is part of the BD family of phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 651 nm and an emission maximum (Em Max) at 660 nm. APC is designed to be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 660 nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
