    Product Information

    Product Description

    This Cell Signaling Technology® antibody is conjugated to mFluor™ Violet 510 fluorescent dye under optimal conditions and formulated at 200 µg/mL. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated #39197

    Fluorescent Properties

    • ← Excitation: 412 nm ← Emission: 505 nm

    Product Usage Information

    SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays.

    Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate.

    Storage

    Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

    Specificity / Sensitivity

    NK1.1/CD161 (E6Y9G) Rabbit mAb (SignalFlex™ mFluor™ Violet 510 Conjugate) recognizes endogenous levels of total CD161c protein from C57BL/6, SJL, and NZW mice, but not from BALB/c and 129S6 mice. Mice from other strains have not been tested. This antibody is predicted to cross-react with CD161b and may cross-react with CD161a protein in some mouse strains.

    Species Reactivity:

    Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of mouse NK1.1/CD161 protein.

    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).
    There is a family of Klrb1 genes in rodents (7). PK136 antibody recognizes a specific epitope on mouse KLRB1b/c, also referred to as NK1.1, and is commonly used for detection of mouse NK cells in certain mouse strains (CE, B6, NZB, C58, Ma/My, ST, SJL, FVB). However, the epitope is absent in other mouse strains (BALB/c, AKR, CBA, C3H, DBA, 129) (8).
