APC-R700 Mouse Anti-Human CD8

Multiparameter flow cytometric analysis of Human CD8 expression on human peripheral blood leucocyte populations. Human whole blood was stained with either BD Horizon™ APC-R700 Mouse IgG1, κ Isotype Control (Cat. No. 564974; Left Plot) or BD Horizon APC-R700 Mouse Anti-Human CD8 antibody (Cat. No. 566857; Right Plot). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). A two-parameter pseudocolor density plot showing the correlated expression of CD8 (or Ig Isotype control staining) versus side-light scatter (SSC-A) signals was derived from gated events with the forward and side-light scatter characteristics of intact leucocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

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 the dye under optimum conditions and unconjugated antibody and free dye 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. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.

HIT8a

The HIT8a monoclonal antibody specifically binds to CD8a (CD8α). CD8α is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily. CD8α is expressed by the majority of thymocytes, by subpopulations of  αβ T cells and γδ T cells and by some NK cells. Cell surface CD8α is expressed either as a disulfide-linked homodimer (CD8αα) or as a heterodimer (CD8αβ) when disulfide-bonded to a CD8 beta chain (CD8β). CD8-positive αβ T cells coexpress both CD8αα homodimers and CD8αβ heterodimers whereas some γδ T cells and NK cells express CD8αα homodimers.  CD8 plays important roles in T cell activation and selection. The extracellular IgSF domain of CD8α binds to a non-polymorphic determinant on HLA class I molecules (α3 domain) and enables CD8 to function as a co-receptor with MHC class I-restricted TCR during T cell recognition of antigen. The cytoplasmic domain of CD8α associates with Lck, a Src family protein tyrosine kinase that is involved in intracellular signaling. Clones  HIT8a and RPA-T8 are not cross-blocking.

This antibody 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.
