Anti nk1.1 pk136

Manufactured by BD
Sourced in United States

Anti-NK1.1 (PK136) is a laboratory reagent used for the identification and detection of NK1.1-positive cells in mice. It is a monoclonal antibody that specifically binds to the NK1.1 antigen expressed on natural killer cells and a subset of T cells in mice. This reagent can be used in various immunological techniques, such as flow cytometry, immunohistochemistry, and cell sorting, to study the role of NK1.1-positive cells in biological processes.

Spleen cells from BALB/c, C57BL/6, BALB.B6-CT-1, BALB.B6-CT-6, BALB.B6-CT-12 and BALB.B6-CT-13 mice were incubated with anti-CD16 antibody (Fc-block), washed and then stained with PE-conjugated anti-CD49b (DX-5) and PE-CY5-conjugated anti-TCR (H57-597) antibodies. Some samples were simultaneously stained with other antibodies such as FITC-conjugated anti-Ly49A (A1), Ly49D (4E5), Ly49G2 (Cwy-e), Ly49I (YLI-90), anti-NKG2A/C/E (20d5) or anti-NK1.1 (PK136) for 1 h on ice (all antibodies and conjugates are from BD Pharmingen, San Diego, CA, USA). The cells were then washed twice, resuspended in PBS and analysed in a FACScalibur cytofluorometer (BD Biosciences, NJ) using CellQuest software. Viable lymphocytes were gated by forward and side scatter.

Cell surface staining was performed using the following antibodies: anti-CD11b (M1/70, Miltenyi Biotec), anti-CD11c (N418, BioLegend) anti-CD3 (17A2, eBioscience), anti-CD49b (DX5, eBioscience), anti-CD69 (H1.2 F3, eBioscience), anti-CD86 (GL-1, BioLegend), anti-MHC-II (M5/114.15.2, Miltenyi Biotec), anti-NK1.1 (PK136, BD Bioscience). Dead cells were excluded from analysis (positive for fixable viability dye, eBioscience). For detection of activated T cells splenocytes were stained with anti-CD4 (GK1.5, eBioscience), anti-CD8 (53–6.7, eBioscience), anti-CD43 (1B11, BioLegend) and anti-CD62L (MEL-14, eBioscience). Intracellular IFN-γ (XMG1.2, Miltenyi Biotec), IL-2 (JES6-5H4, Miltenyi Biotec) and TNF-α (MP6-XT22, BioLegend) staining was performed as described [28 (link),29 (link)]. Data were acquired on LSR II flow cytometer (BD Bioscience) and analyses were performed using FACSDiva (BD Bioscience) and Flow Jo (Tree Star, USA) software.

Equivalent cell numbers were treated with Fc block (BD Biosciences) and surface stained with combinations of anti-MHC II (M5/114.15.2), anti-CD11c (N418), anti-CD11b (M1/70), and anti-Ly6c (HK1.4) antibodies (eBiosciences) (neutrophils) or anti-Ly6g (1A8), anti-MHC class II (AF6–120.1), anti-CD11c (N418; eBioscience), anti-Ly6c (ER-MP20; AbD Serotech), anti-CD11b (M1/70; BD Biosciences), anti-CD4 (RM4.5; BD Biosciences), anti-NK1.1 (PK136; BD Biosciences), αβT cell receptor (H57–597; BD), anti-CD8 (53–6.7; eBioscience), anti-iNOS (M-19; Santa Cruz Biotechnology), or anti-TNF-α (MP6-XT22; BD Biosciences) (tipDCs, CD4+ T cells, CD8+ T cells) as previously described [37 (link),66 (link)]. CD8+ T cells were stained with tetramers specific for the DbPB1-F262–70 epitope for 1 h at room temperature prior to surface staining with the monoclonal antibodies as previously described [66 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
