PE Mouse Anti-Human CD161
PE Mouse Anti-Human CD161

Multiparameter flow cytometric analysis of CD161 expression on human peripheral blood leucocyte populations. Human peripheral blood was stained with either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human CD161 antibody (Cat. No. 566843; Right Plot). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The two-parameter pseudocolor density plot showing the correlated expression of CD161 (or Ig Isotype control staining) versus side light scatter signals (SSC-A) was derived from gated events with the forward and side light-scatter characteristics of intact leucocyte populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

PE Mouse Anti-Human CD161

Two-color flow cytometric analysis of CD161 expression on human peripheral blood lymphocytes. Human peripheral blood was stained with APC Mouse Anti-Human CD56 antibody (Cat. No. 555518) and either PE Mouse IgG1, κ Isotype Control (Cat. No. 554680; Left Plot) or PE Mouse Anti-Human CD161 antibody (Cat. No. 566843; Right Plot). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plot showing the correlated expression of CD56 versus CD161 expression (or Ig Isotype control staining) was derived from gated events with forward and side light-scatter characteristics of intact human peripheral blood lymphocytes. 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 with R-PE under optimum conditions, and unconjugated antibody and free PE 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.
  5. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

HP-3G10

The HP-3G10 monoclonal antibody specifically recognizes human CD161 which is also known as Natural killer cell surface protein P1A (NKR-P1A or NKRP1A) or C-type lectin domain family 5 member B (CLEC5B). CD161 is expressed on the cell surface as an 80 kDa disulfide-linked homodimeric type II transmembrane glycoprotein. It is encoded by KLRB1 (Killer cell lectin-like receptor subfamily B member 1) which belongs to the Ca2+-dependent C-type lectin superfamily. CD161 is expressed on NK cells and on subsets of CD4+ and CD8+ αβ T cells, NKT cells, γδ T cells, CD3+ thymocytes, and fetal liver cells. CD161 is preferentially expressed on memory/effector T cells. CD161 can reportedly inhibit NK cell-mediated cytotoxicity and IFN-γ production. Lectin-like transcript 1 (LLT-1), encoded by CLEC2D (C-type lectin domain family 2 member D), has been described as a ligand for CD161. LLT-1 is expressed on some activated dendritic cells (DC) and B cells.

PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
