Specificity / Sensitivity

CD161/KLRB1 (HP-3G10) Mouse mAb (PE Conjugate) recognizes endogenous levels of total CD161/KLRB1 protein. This antibody detects an epitope within the extracellular domain.

Species Reactivity:

Human

Source / Purification

This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography. The purified antibody was conjugated under optimal conditions, with unreacted dye removed from the preparation.

Background

CD161/KLRB1 (Killer cell lectin-like receptor subfamily B member 1, also known as CLEC5B and NKR-P1A) is a type II transmembrane protein that is expressed on the majority of Natural Killer (NK) cells, NK T cells, and some T lymphocytes (1). CD161/KLRB1 is also expressed on Th17 cells, promotes their generation, and modulates their function (2). Engagement with its ligand lectin-like transcript 1 (LLT1) inhibits NK cell function, while LLT1 and CD161/KLRB1 interaction in the presence of a TCR signal enhances IFN-gamma production by T cells (3,4). There are several different CD161 isoforms in rodents and some function as activating receptors as well (5,6).

This HP-3G10 antibody is used for flow cytometric analysis of CD161/KLRB1 expression on NK, NKT, and various subsets of T cells.
