Target

  • Function
    Plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Plays an important role in killing other cells that are recognized as non-self by the immune system, e.g. in transplant rejection or some forms of autoimmune disease. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes.
  • Involvement in disease
    Defects in PRF1 are the cause of hemophagocytic lymphohistiocytosis familial type 2 (FHL2) [MIM:603553]; also known as HPLH2. Familial hemophagocytic lymphohistiocytosis (FHL) is a genetically heterogeneous, rare autosomal recessive disorder. It is characterized by immune dysregulation with hypercytokinemia and defective natural killer cell function. The clinical features of the disease include fever, hepatosplenomegaly, cytopenia, hypertriglyceridemia, hypofibrinogenemia, and neurological abnormalities ranging from irritability and hypotonia to seizures, cranial nerve deficits, and ataxia. Hemophagocytosis is a prominent feature of the disease, and a non-malignant infiltration of macrophages and activated T lymphocytes in lymph nodes, spleen, and other organs is also found.
  • Sequence similarities
    Belongs to the complement C6/C7/C8/C9 family.
    Contains 1 C2 domain.
    Contains 1 EGF-like domain.
    Contains 1 MACPF domain.
  • Domain
    The C2 domain mediates calcium-dependent binding to lipid membranes. A subsequent conformation change leads to membrane insertion of beta-hairpin structures and pore formation. The pore is formed by transmembrane beta-strands.
  • Post-translational
    modifications
    N-glycosylated.
  • Cellular localization
    Cytoplasmic granule lumen. Secreted. Cell membrane. Endosome lumen. Stored in cytoplasmic granules of cytolytic T-lymphocytes and secreted into the cleft between T-lymphocyte and target cell. Inserts into the cell membrane of target cells and forms pores. Membrane insertion and pore formation requires a major conformation change. May be taken up via endocytosis involving clathrin-coated vesicles and accumulate in a first time in large early endosomes.

      ab16074 staining Perforin in Mouse lymphoid tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with a zinc-based fixative and blocked with rodent block-M for 20 minutes at 20°C. Samples were incubated with primary antibody (1/50 in TBS + 0.05% Tween20) for 1 hour at 20°C. A HRP-conjugated Goat polyclonal was used as the secondary antibody.

    Question

    Phone call requesting information on which antigen retrieval would be recommended to use the Anti-Perforin antibody [CB5.4] (ab16074).

    Answer

    I can confirm that the Anti-Perforin antibody [CB5.4] (ab16074) has been used with citrate buffer (pH 6) when performing staining of paraffin embedded sections. I would however advise that it may be worthwhile to optimize this for your particular tissue preparations. Therefore using both citrate buffer (pH 6) as well as Tris-EDTA (pH 9) and seeing which provides the best results for you.

    13) Detection method



    14) How many times have you run this staining? 2 titrations 1.: 1:50, 1:500, 1:1000, 2.: 1:10, 1:20, 1;50

    Do you obtain the same results every time? no

    What steps have you altered to try and optimize the use of this antibody?

    altered washing steps for 2nd titration (did not dip slides into PBS bath but dribbled PBS on top and tapped it off again, also 2 times
