Detects mouse CD161/NK1.1 expressed specifically in the C57/B6 mouse strain. No detection of CD161/NK1.1 was observed in the BALB/c mouse strain. In direct ELISAs, less than 5% cross-reactivity with recombinant mouse (rm) KLRB-1B is observed.

KLRB-1C, also known as NK1.1, CD161c, Ly-55, and NKR-P1c, is a 28 kDa type 2 transmembrane protein in the killer cell lectin-like receptor family. CD161 is expressed as a disulfide-linked homodimer on the surface of NK cells and subpopulations of NKT, CD4+, CD8+, and gamma /δ T cells. Its cross-linking on NK cells induces cytolytic activity, and on CD4 cells it promotes IgE production and the expansion of Th2 responses. Mature mouse CD161 consists of a 45 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 157 aa extracellular domain with one C-type lectin domain.
