IHC-P 1/50.
  • Application notes
    Is unsuitable for ICC or ICC/IF.
  • Target

    • Function

      May play a role in the response to environmental stress. Appears to act upstream of the JUN N-terminal pathway. May play a role in hematopoietic lineage decisions and growth regulation.
    • Tissue specificity

      Expressed primarily in hematopoietic organs, including bone marrow, spleen and thymus. Also expressed at very low levels in lung, kidney, mammary glands and small intestine.
    • Sequence similarities

      Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. STE20 subfamily.
      Contains 1 CNH domain.
      Contains 1 protein kinase domain.

    • ab33910 staining MAP4K1/HPK1 in human liver tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/50. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at 1/500.

      Negative control 1: PBS in place of primary antibody.
