CD161 antibody

Catalog No. ABIN118295

Product Details anti-CD161 Antibody

Target: CD161 (KLRB1) (Killer Cell Lectin-Like Receptor Subfamily B, Member 1 (KLRB1))

Reactivity: Mouse

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD161 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunoprecipitation (IP), Cytotoxicity Test (CyTox)

Specificity: This antibody (clone PK136) recognises the NK1.1 cell surface antigen. Although previously thought to recognise only CD161c, recent data has shown that the PK136 antibody may also react with CD161b. CD161c expression itself is strain specific in mice, but recognition of CD161b by PK136 appears to be even more complex, as only some CD161b positive strains are labelled by the antibody. Engagement of CD161c has been reported to have activating function in NK cells, whilst engagement of CD161b is inhibitory. This antibody is useful for the identification of NK cells in selected strains of mice (positive on C57BL, FVB/N and NZB, but negative on AKR and BALB/c) and is also expressed by rare subsets of T cells and monocytes. The antibody has also been used for in vivo depletion of NK cells and in vitro activation of NK cells.

Target Details for CD161

Target: CD161 (KLRB1) (Killer Cell Lectin-Like Receptor Subfamily B, Member 1 (KLRB1))

Alternative Name: CD161 / KLRB1 (KLRB1 Products)

Background: NK1.1 is a cell surface glycoprotein encoded by members of the NKR-P1 gene family. In the mouse the NKR-P1 family has three members, NKR-P1A, -B and -C, whilst in the human only one member has been identified. The human protein has received the designation CD161, and the mouse proteins have been referred to as CD161a, -b, -c etc.Synonyms: C-type lectin domain family 5 member B, CLEC5B, HNKR-P1a, Killer cell lectin-like receptor subfamily B member 1, NKRP1A, Natural killer cell surface protein P1A
