  • 機能

    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.

  • 関連疾患

    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.

  • 配列類似性

    Belongs to the complement C6/C7/C8/C9 family.
    Contains 1 C2 domain.
    Contains 1 EGF-like domain.
    Contains 1 MACPF domain.

  • ドメイン

    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.

  • 翻訳後修飾

    N-glycosylated.

  • 細胞内局在

    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.

    Question

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

    Read More
    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.

    Question

    Hier das ausgefüllte questionnaire, im Anhang die Bilder (nur der rote Kanal =Perforin):

    2nd rab rat ist das Bild der Kontrollfärbung, wo nur 2. Antikörper gefärbt wurden. Die Zahlen Perf-50 heißt, dass der Primärantikörper gegen Perforin in einer Verdünnung von 1:50 verwendet wurde.

    Das Bild 12-08-07 spleen perf 50 cd8 50 stammt aus der ersten Färbung (Titration 1) die beiden anderen aus der 2. Färbung



    1) Abcam product code ab 16074



    2) Abcam order reference number or product batch number



    3) Description of the problem

    not sure whether the signal is just background, since control without primary antibodies but with secondary antibodies also gives a signal (see attached pictures)



    4) Sample preparation:

    Species mouse, spleen embedded in tissue tek, frozen at -80°C

    Type of sample: Fresh frozen sections (5µm)

    Sample preparation: fixed in acetone for 10 min at RT, encirceled with DAKO pen, blocked with serum, incubation with primary antibodies, washing, incubation with secondary antibodies, washing, incubation with Hoechst, washing, cover slipping with Glycerin/Gelatine

    Positive control staining of spleen

    Negative control only secondary antibodies



    5) Fixation step

    Yes

    If yes: fixed in acetone

    Fixation time10 min

    Fixation temperature RT



    6) Antigen retrieval method

    none



    7) Permeabilization method: no

    Did you do a permeabilization step (details please) or add permeabilizing agent in any dilution buffers?

    Permeabilizing agent and concentration:





    8) Blocking agent (eg BSA, serum…): serum (goat or chicken, depending on the second antibody)

    Concentration 1/100

    Blocking time at least 10 min

    Blocking temperature RT



    9) Endogenous peroxidases blocked? no

    Endogenous biotins blocked? no



    10) Primary antibody (If more than one was used, describe in “additional notes”) :

    Concentration or dilution 1:10, 1:20, 1:50, 1:50, 1:500, 1:1000

    Diluent buffer PBS

    Incubation time 1 hour



    11) Secondary antibody: anti-rat Alexa 594 (invitrogen A21471)

    Species:

    Reacts against: rat

    Concentration or dilution 1:200

    Diluent buffer PBS

    Incubation time 1 hour

    Fluorochrome or enzyme conjugate Alexa 594



    12) Washing after primary and secondary antibodies:

    Buffer: PBS

    Number of washes 2 times in a PBS bath



    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



    Falls Sie noch etwas benötigen, werde ich es Ihnen zukommen lassen.

    Vielen Dank für Ihre Antwort und für diese weiteren Informationen.

    Da Ihrem Protokoll bis auf Kleinigkeiten nichts hinzuzufügen ist, muss ich leider davon ausgehen, dass der Antikörper nicht so funktioniert hat, wie er sollte.

    Ich weiß, dass Sie viel Zeit für diese Experimente verwendet haben und möchte Ihnen daher einen kostenlosen Antikörperoder einen Gutschein als Ersatz anbieten. Würden Sie mir bitte mitteilen, welche Alternative Sie bevorzugen?

    Vielen Dank für Ihre Kooperation und Hilfsbereitschaft. Ich freue mich bald wieder von Ihnen zu hören.
