ターゲット情報

  • 機能

    Most upstream protease of the activation cascade of caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death. Binding to the adapter molecule FADD recruits it to either receptor. The resulting aggregate called death-inducing signaling complex (DISC) performs CASP8 proteolytic activation. The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases. Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC. Cleaves and activates CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10. May participate in the GZMB apoptotic pathways. Cleaves ADPRT. Hydrolyzes the small-molecule substrate, Ac-Asp-Glu-Val-Asp-
    -AMC. Likely target for the cowpox virus CRMA death inhibitory protein. Isoform 5, isoform 6, isoform 7 and isoform 8 lack the catalytic site and may interfere with the pro-apoptotic activity of the complex.

  • 組織特異性

    Isoform 1, isoform 5 and isoform 7 are expressed in a wide variety of tissues. Highest expression in peripheral blood leukocytes, spleen, thymus and liver. Barely detectable in brain, testis and skeletal muscle.

  • 関連疾患

    Defects in CASP8 are the cause of caspase-8 deficiency (CASP8D) [MIM:607271]. CASP8D is a disorder resembling autoimmune lymphoproliferative syndrome (ALPS). It is characterized by lymphadenopathy, splenomegaly, and defective CD95-induced apoptosis of peripheral blood lymphocytes (PBLs). It leads to defects in activation of T-lymphocytes, B-lymphocytes, and natural killer cells leading to immunodeficiency characterized by recurrent sinopulmonary and herpes simplex virus infections and poor responses to immunization.

  • 配列類似性

    Belongs to the peptidase C14A family.
    Contains 2 DED (death effector) domains.

  • ドメイン

    Isoform 9 contains a N-terminal extension that is required for interaction with the BCAP31 complex.

  • 翻訳後修飾

    Generation of the subunits requires association with the death-inducing signaling complex (DISC), whereas additional processing is likely due to the autocatalytic activity of the activated protease. GZMB and CASP10 can be involved in these processing events.
    Phosphorylated upon DNA damage, probably by ATM or ATR.

Tissue  underwent fixation in paraformaldehyde, heat mediated antigen retrieval in 10mM Citrate buffer pH 6.0, permeabilization in 0.1% Triton X-100 prior to blocking in 10% serum for 20 minutes at 22°C. The primary antibody, diluted 1/50 in PBS with 2% BSA and incubated with sample, for 45 minutes at 22°C. An Avidin-peroxidase conjugated horse polyclonal to rabbit Ig, was used undiluted as the secondary antibody.

    Question

    I am not clear that whether ab4052(anti-caspase 8) will be recognizing full length caspase 8(pro-caspase 8). Does this antibody work for cell culture staining (IFC)? Thanks

    Read More
    Answer

    Thank you for contacting us.

    I'm afraid we are unable to determine if the antibody is specific to the active form only of caspase 8 or the pro-form as it has only been tested in IHC. We also haven't tested it in staining cells (ICC/IF). Most likely it will work, as it is a simliar application to IHC, but we can't guarantee ICC/IF since it is untested.

    I'm sorry I cannot be of further assistance on this occasion.

    Question

    Christian is visting Cambridge (and Abcam of course), so I forward our customers reply to your suggestion: "... Dear abcam-team Thank you for your kind reply concerning the antibody anti-Caspase 8 / Flice no. AB4052. I have used the PBST medium as diluent for the antibodies, but again failed to stain apoptotic cells. Further changes in our protocol were also not successful. I got no staining at all in any slide. You successfully used this antibody in immunohistochemistry in paraffin embedded murine tissue. Would it be possible to get your staining-protocol? It would help me very much. Thanks in advance J. Podlech .." Hoepfully you can provide such a protocol?

    Read More
    Answer

    I can confirm that the customer's protocol is adequate and should work. However, we have the following suggestions: 1. Try using another tissue besides liver. We recommend stomach. 2. The customer is using home brewed detection system. The sensitivity of the system may therefore not be adequate. I would suggest the followings: try using lower dilution of the primary antibody or try using more concentrated link (goat anti rabbit, 1:500 may be too diluted). Please let me know if the customer still has problems with the positive control and we can arrange for a replacement vial,

    Question

    follow up to previous correspondance: The antibody was stored in our refrigerator (4°C) and used the other day, after delivery. The antigen retrieval step was performed as we usually do it. That means a boiling step of about 5 min and cooling for about 1 hour in the unmasking solution. It works very well with a lot of antibodies in our hands. A permeabilisation step was not done, because I don't think that this step is really necessary for formalin-fixed and paraffin-embedded tissue. The antibody was diluted in TBS. The immunohistochemistry protocol includes a serum block (10% goat serum in TBS) before incubation with the first antibody. I hope this further information is helpful. Thank you very much for your efforts.

    Answer

    Thank you for those further protocol details, I would like to recommend diluting the blocking serum, primary and secondary antibodies in PBST containing triton x100 (0.3%v/v) to promote permeabilization of the tissue and enable better penetration of the antibody. Please let me know if you still have problems with this antibody and we can offer you a replacement or credit note or refund if you purchased the antibody in the last 90 days,

Detection with the Avidin-Biotin-Complex-method (peroxidase) and DAB as the substrate after incubation with the secondary antibody. HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 4 HAVE YOU RUN A "NO PRIMARY" CONTROL? Yes DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes ADDITIONAL NOTES Other anti caspase antibody work well in this system

    Answer

    I'm very sorry to hear you are having problems with ab4052, thank you for taking the time to fill in the online questionnaire. Could you please tell me: -how the antibody was stored? - how long the antigen retrieval step was? - if you have done a permeabilization step? - the buffer used to dilute the antibodies? -what blocking was done (BSA/serum? HRP block?)? My apologies for the delay, thank you for your patience, I look forward to hearing from you,

    Question

    Will this product detect both the active an inactive form of caspase 8?

    Read More
    Answer

    Thank you for your enquiry. This antibody recognizes the full length inactive proenzyme (55 kDa). While this antibody has also been shown to detect the processed forms of Caspase 8 (which associate to form the active enzyme), its specific reaction with the active form is unknown to us. If you have any further questions then please do not hesitate to get back in touch with us.
