    • ターゲット情報

    • 機能
      Receptor for TNFSF6/FASLG. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. FAS-mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. The secreted isoforms 2 to 6 block apoptosis (in vitro).
    • 組織特異性
      Isoform 1 and isoform 6 are expressed at equal levels in resting peripheral blood mononuclear cells. After activation there is an increase in isoform 1 and decrease in the levels of isoform 6.
    • 関連疾患
      Defects in FAS are the cause of autoimmune lymphoproliferative syndrome type 1A (ALPS1A) [MIM:601859]; also known as Canale-Smith syndrome (CSS). ALPS is a childhood syndrome involving hemolytic anemia and thrombocytopenia with massive lymphadenopathy and splenomegaly.

        Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue labelling Fas with ab133619 at a dilution of 1:500. Heat mediated antigen retrieval was performed using AR9 antigen retrieval solution, and microwave treatment for 15 min at 20% power. Anti-Rabbit/Mouse HRP polymer (PerkinElmer Opal Polymer HRP Ms Plus Rb) was used as secondary antibody. Opal tyramide amplification was performed using Opal 520 fluorophore. Counterstained with DAPI stain. Image scanned with Vectra 3.0 and analyzed via Phenochart software.

      Question

      SEARCHING ANTIBODY FOR FLOW CYTOMETRY AGAINST HUMAN CELLS BUT NOT MOUSE CELLS

      Dear,
      Parhaps ab133619 will also work. This CD95, it is the same as Fas, right? If so, this should be expressed on the outer membrane by PC3 cells, according to literature, so that may be a safer one than the cytokeratin.
      Best,
      Thank you very much for this info. ab32118 may be a good candidate.
      I have one major question though, which I cannot really find in literature. I am using PC3 cells as human cancer cells. They are reported to express cytokeratin 18. However, is this protein present at the cell surface in living cells? I find that in most studies cells are fixed with for example aceton, before the staining of keratins. So when you tested this antibody in flow cyt, on which cells was this tested, and were those cells fixed/permeabilized in some way or were they alive?
      Thank you.

      Answer

      Thank you very much for your answer.
      I have contacted the laboratory to gather some more information in regards to the species testing of these antibodies. I am sorry it has taken so long time. Have you already proceeded meanwhile?
      In regards to the cytokeratin 18 antibody - as far as I know, the cytokeratins are all cytoplasmic. The ab32118 has been tested in flow cytometry on permeabilized cells (with methanol).
      In regards to the CD95 antibody ab133619, we do not think it crossreacts with mouse and rat as the immunogen shares only 45% identity with mouse and rat CD95. However there was a signal in mouse heart for which we could not determine whether it was specific or not. I am very sorry for not being able to provide you with a better answer still. What I however would like to offer is a testing discount: you would buy this antibody and test it. You would then provide the feedback via an Abreview. Once we have the feedback, you would receive an antibody of your choice from our catalog for free.
      If such a testing would interest you, please do let me know and I will describe you the offer in more details.
      If however you prefer looking at other antibodies, please let me know as well. I would be pleased to investigate also other antibodies of the list for you (and I would expect it being faster this time .. ).
      Please let me know if you have any question. I look forward to hear back from you.
