APC-Cy™7 Rat Anti-Mouse Vα2 TCR
APC-Cy™7 Rat Anti-Mouse Vα2 TCR

Flow cytometric analysis of Vα2 TcR on mouse lymph node cells.  Lymph node cells from BALB/c mice were stained with FITC Rat Anti-Mouse CD4 (Cat. No. 553046) and FITC Rat Anti-Mouse CD8b.2 (Cat. No. 553040) in addition to either a APC-Cy™7 Rat IgG2a, λ isotype control (left panel) or with the APC-Cy™7 Rat Anti-Mouse Vα2 TcR antibody (right panel).  Dot plots were derived from gated events based on light scattering characteristics for lymph node cells.  Flow cytometry was performed on a BD™ LSR II flow cytometry 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 with APC-Cy7 under optimum conditions, and unconjugated antibody and free APC-Cy7 were removed.

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. Warning: Some APC-Cy7 and PE-Cy7 conjugates show changes in their emission spectrum with prolonged exposure to formaldehyde. If you are unable to analyze fixed samples within four hours, we recommend that you use BD™ Stabilizing Fixative (Cat. No. 338036).
  4. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
  5. This conjugated product is sold under license to the following patent: US Patent No. 5,714,386.
  6. Cy is a trademark of Amersham Biosciences Limited. This conjugated product is sold under license to the following patents: US Patent Nos. 5,486,616; 5,569,587; 5,569,766; 5,627,027.
  7. This product is subject to proprietary rights of Amersham Biosciences Corp. and Carnegie Mellon University and made and sold under license from Amersham Biosciences Corp. This product is licensed for sale only for research. It is not licensed for any other use. If you require a commercial license to use this product and do not have one return this material, unopened to BD Biosciences, 10975 Torreyana Rd, San Diego, CA 92121 and any money paid for the material will be refunded.
  8. APC-Cy7 tandem fluorochrome emission is collected in a detector for fluorescence wavelengths of 750 nm and higher.
  9. APC-Cy7 is a tandem fluorochrome composed of Allophycocyanin (APC), which is excited by laser lines between 595 and 647 nm and serves as an energy donor, coupled to the cyanine dye Cy7™, which acts as an energy acceptor and fluoresces at 780 nm. BD Biosciences Pharmingen has maximized the fluorochrome energy transfer in APC-Cy7, thus maximizing its fluorescence emission intensity, minimizing residual emission from APC, and minimizing required electronic compensation in multilaser-laser flow cytometry systems. Note: Although every effort is made to minimize the lot-to-lot variation in residual emission from APC, it is strongly recommended that every lot be tested for differences in the amount of compensation required and that individual compensation controls are run for each APC-Cy7 conjugate.
  10. 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.

B20.1

The B20.1 monoclonal antibody specifically binds to most members of the Vα2 T-cell Receptor (TCR) subfamily in mice having the a, b, and c haplotypes of the Tcrb gene complex. B20.1 antibody may crossreact with Vδ8 TCR, which shares >90% sequence homology with Vα2 TCR. Levels of B20.1+ T cells appear to be influenced by Vα haplotypes. Moreover, the frequencies of Vα2+ CD8+ and CD4+ T cells are influenced by H-2 haplotypes.

APC-Cy7
APC-Cy7 dye is a part of the BD APC red family of dyes. This tandem fluorochrome is comprised of a Allophycocyanin (APC) donor that has excitation maxima (Ex Max) of 651 nm and an acceptor dye, Cy™7, with an emission maximum (Em Max) at 779 nm. APC-Cy7 can be excited by the Red (627-640 nm) laser and detected using an optical filter centered near 780 nm (e.g., a 760/60 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
