The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use at an assay dependent concentration.
Flow Cyt Use at an assay dependent concentration.

ab199376 - Rabbit monoclonal IgG (Low endotoxin, Azide free), is suitable for use as an isotype control with this antibody.

IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

See IHC antigen retrieval protocols.

WB Use at an assay dependent concentration. Predicted molecular weight: 78 kDa.


  • Function
    Catalyzes the first step in leukotriene biosynthesis, and thereby plays a role in inflammatory processes.
  • Pathway
    Lipid metabolism; leukotriene A4 biosynthesis.
  • Sequence similarities
    Belongs to the lipoxygenase family.
    Contains 1 lipoxygenase domain.
    Contains 1 PLAT domain.
  • Post-translational
    Serine phosphorylation by MAPKAPK2 is stimulated by arachidonic acid. Phosphorylation on Ser-523 by PKA has an inhibitory effect. Phosphorylation on Ser-272 prevents export from the nucleus.
  • Cellular localization
    Cytoplasm. Nucleus matrix. Nucleus membrane. Shuttles between cytoplasm and nucleus. Found exclusively in the nucleus, when phosphorylated on Ser-272. Calcium binding promotes translocation from the cytosol and the nuclear matrix to the nuclear envelope and membrane association.

  • This IHC data was generated using the same anti-5 Lipoxygenase antibody clone, EP6072(2), in a different buffer formulation (cat# ab169755).

    ab169755 staining 5 Lipoxygenase in Human tonsil tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed and paraffin-embedded, antigen retrieval was by heat mediation in Tris/EDTA buffer pH9. Samples were incubated with primary antibody (1/100). An undiluted HRP-conjugated mouse anti-rabbit IgG was used as the secondary antibody. Tissue counterstained with Hematoxylin. PBS was used in the negative control rather than the Primary antibody.
