• Product name
    Anti-Flt3 ligand antibody [EP1140Y]
    See all Flt3 ligand primary antibodies
  • Description
    Rabbit monoclonal [EP1140Y] to Flt3 ligand
  • Host species
  • Specificity
    The antibody has been tested against recombinant protein in western blotting, we do not have data regarding recognition of endogenous protein. We suggest K562 and HL-60 cells could be expressing Flt3 ligand. The antibody was raised against the extracellular domain of the protein, however please note permeabilisation in FACS greatly improves the signal.
  • Tested applications
    Suitable for: ICC/IF, WB, Flow Cyt, IHC-Pmore details
  • Species reactivity
    Reacts with: Human, Rhesus monkey
  • Immunogen

    A synthetic peptide corresponding to residues within human Flt3 ligand.

  • Positive control
    • IHC: Human tonsil tissue; human liver. WB: recombinant protein ICC/IF: MCF7 FC: Hela

    Blocking and diluting buffer: 5% NFDM/TBST.

  • Flow Cytometry analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling Flt3 ligand with purified ab52648 at 1:50 dilution. Cells were fixed with 4% Paraformaldehyde. A Goat anti rabbit IgG (Alexa Fluor ® 488) secondary antibody was used at 1:2000 dilution. Isotype control - Rabbit monoclonal IgG (Black). Unlabeled control - Cell without incubation with primary antibody and secondary antibody (Blue).
  • Immunocytochemistry/ Immunofluorescence analysis of MCF7 (Human breast adenocarcinoma epithelial cell) cells labeling Flt3 ligand with Purified ab52648 at 1:100 dilution. Cells were fixed in 100% Methanol and permeabilized with None. ab150077 Goat anti rabbit IgG(Alexa Fluor ® 488) was used as the secondary antibody at 1:1000 dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human liver tissue sections labeling Flt3 ligand with Purified ab52648 at 1:180 dilution. Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0). Tissue was counterstained with Hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control.
  • Unpurified ab52648 staining Flt3 ligand in Rhesus monkey brain tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 20% serum for 60 minutes at 20°C; antigen retrieval was by heat mediation in a citrate buffer pH6.0. Samples were incubated with primary antibody (1/100 in 20% Normanl Goat serum in 1x TTBS) for 12 hours at 20°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.
