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.

Images

  • ICC/IF image of ab7203 stained SW480 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab7203, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Answer

Thank you for contacting us and your patience, as we were closed over Easter.
I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.
As positive control, I can either recommend either fresh PBL or inflamed tissues, as well as the YT-Indy cell line - see either SwissProt or our datasheet of the ab86319 for reference: http://www.uniprot.org/uniprot/P10820 https://www.abcam.com/index.html?datasheet=86319
We normally do not send out positive controls for our antibodies. However we do guarantee all our products to work as stated on the datasheet. I would therefore suggest that we firstly investigate your results.
In order to do so, I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.
I look forward to receiving your reply.

Answer

We passed your enquiry on to the originator of this antibody and they have replied with the following response. If you have any further questions, please let us know. Many rat kidney models are known to contain anti-GBM antibody, which has approximately 20% cross-reactivity with anti-rabbit IgG. Since anti-rabbit IgG is the secondary Ab used to detect this rabbit polyclonal to perforin, there would be background if the sample was not well-denatured. A complete denaturing of the sample should improve the specificity.
