Alexa Fluor® 700 Mouse Anti-Mouse NK1.1

Flow cytometric analysis of NK1.1 expression on mouse splenocytes.  Splenocytes from C57BL/6 mice were stained with FITC Hamster Anti-Mouse CD3e antibody (Cat. No. 553061) and either Alexa Fluor® 700 Mouse IgG2a, κ isotype control (Cat. No. 557880; left panel) or Alexa Fluor® 700 Mouse Anti-Mouse NK1.1 (Cat. No. 560515; right panel).  Two-color dot plots were derived from gated events based on the forward and side light-scattering characteristics of viable splenocytes.  Flow cytometry was performed on a BD FACSCanto™ system

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® 700 under optimum conditions, and unreacted Alexa Fluor® 700 was removed.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. Alexa Fluor® 700 has an adsorption maximum of ~700nm and a peak fluorescence emission of ~720nm. Before staining cells with this reagent, please confirm that your flow cytometer is capable of exciting the fluorochrome and discriminating the resulting fluorescence.
  5. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
  6. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents.

PK136

In the mouse, at least three members of the Klrb (Killer cell lectin-like receptor, subfamily b; formerly NKR-P1) gene family have been identified (Klrb1a/NKR-P1A, Klrb1b/NKR-P1B, and Klrb1c/NKR-P1C); but in the human gene family, a single homologue has been designated KLRB1, NKR-P1A, or CD161. The KLRB1/NKR-P1 family of proteins are type-II-transmembrane C-type lectin receptors. KLRB1C/NKR-P1C activates NK-cell cytotoxicity, while KLRB1B/NKR-P1B functions as an inhibitory receptor. KLRB1B/NKR-P1B protein has intracellular Immunoreceptor Tyrosine-based Inhibitory Motif (ITIM), while KLRB1C/NKR-P1C lacks ITIM and activates via association with Fc Receptor γ chain. Strikingly, KLRB1B/NKR-P1B and KLRB1C/NKR-P1C share 96% amino acid sequence identity in their extracellular C-type lectin domains. The PK136 antibody reacts with the NK-1.1 surface antigen (CD161c) encoded by the Klrb1c/NKR-P1C gene expressed on natural killer (NK) cells in selected strains of mice (eg, C57BL, FVB/N, NZB, but not A, AKR, BALB/c, CBA/J, C3H, C57BR, C58, DBA/1, DBA/2, NOD, SJL, 129) and the CD161b antigen encoded by the Klrb1b/NKR-P1B gene expressed only on Swiss NIH and SJL mice, but not on C57BL/6. Expression of KLRB1C/NKR-P1C protein is correlated with the ability to lyse tumor cells in vitro and to mediate rejection of bone marrow allografts. The NK-1.1 marker is useful in defining NK cells; however, the antigen is also expressed on a rare, specialized population of T lymphocytes (NK-T cells) and some cultured monocytes. Plate-bound PK136 mAb, in combination with low concentrations of IL-2, induces proliferation of a subset of NK cells.

Alexa Fluor™ 700
Alexa Fluor™ 700 dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 697 nm and an emission maximum (Em Max) at 719-nm. Alexa Fluor™ 700 is designed to be excited by the Red (627–640-nm) laser and detected using an optical filter centered near 720-nm (e.g., a 720/40-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
