Regulatory Status Legend
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+ αâ 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.
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

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 Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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.
