    Immunoprecipitation - Anti-KIR2DL1 + KIR2DL2 antibody [EPR22492-79] - BSA and Azide free (ab255857)

    KIR2DL1 + KIR2DL2 were immunoprecipitated from 0.35 mg of NK-92 (human peripheral blood malignant non-Hodgkin's lymphoma cell line) (treated with 2μM 5-aza-2-deoxycytidine for 48h) whole cell lysate with ab252937 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab252937 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used as secondary antibody at 1/5000 dilution.

    Lane 1: NK-92 (treated as above) whole cell lysate 10 μg (Input). 
    Lane 2: ab252937 IP in NK-92 (treated as above) whole cell lysate. 
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab252937 IP.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 30 seconds.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab252937).

    mmunohistochemical analysis of paraffin-embedded human endometrium tissue labeling KIR2DL1 + KIR2DL2 with a252937 at 1/1000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Positive staining in natural killer (NK) cells in human endometrium (PMID: 7749980) is observed. Counterstained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) ready to use.

    Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized NK-92 (human peripheral blood malignant non-Hodgkin's lymphoma cell line) cells (+/- treatment with 5-aza-2-deoxycytidine (2μM) for 48h) labeling KIR2DL1 + KIR2DL2 with ab252937 at 1/50 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing membranous staining in NK-92 cells treated with 5-aza-2-deoxycytidine (2μM) for 48h. The nuclear counte stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).

    Secondary antibody only control: Used PBS instead of primary antibody, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab252937).

    Goat Anti-Rabbit IgG Fc (Alexa Fluor® 488) preadsorbed (ab150097), at 1/5000 dilution was used as the secondary antibody.

    Cells were stained with rabbit IgG (Left) or ab252937 (Right). Then stained with anti-CD56 conjugated to BV421.

    Gated on viable cells.
