  • 特記事項

    The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in the p53 network, including Chk2, p53R2, p53AIP1, Noxa, PIDD, PID/MTA2, MTBP and PERP, were identified and their genes were cloned recently. PERP, also termed PIGPC1 and THW, is a plasma membrane protein. p53 binds to the promoter of PERP and transcriptionally activates PERP gene then the translated PERP protein mediates the p53 induced apoptosis. The expression of PERP causes cell death. PERP is a mediator of p53 induced apoptosis. PERP has sequence similarity to PMP-22/gas3 and is a new member of the PMP-22/gas3 family.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    Question


    I called earlier to inquire about this product and decided to exchange this order for ab5986 upon hearing that ab48032 would be backordered for awhile. I have tested out ab5986, which is only predicted to work on mouse, on mouse mammary tumors for IF and obtained negative results with two different processing methods; these methods worked perfectly well for ab3945, which I believe has been discontinued by your company. Would I still be able to use the discount code to try out ab48032 on mouse tissue? Thank you.
    Best,

    Answer

    Thank you for your email and for keeping me updated about the situation.
    I'm sorry to hear that ab5986 did not work well with the mouse samples, and it is possible that this antibody just doesn't work with mouse. We have unfortunately removed ab3945 from our catalog, but the discount code for ab48032 is still valid if you would like to try that antibody. The code expires in August, but if you need to extend that date please let me know and I'll be happy to issue you a new code.
    Please let me know if you have any further questions or if there is anything else that we can do for you.

    Answer

    Thank you for the details that you have provided and I'm sorry to hear that you are experiencing difficulty with ab5986. At this point I would like to make the following suggestions to help improve results as you are not seeing any bands. This antibody was characterized for use in Western blotting with A431 lysate and I strongly suggest using this as a positive control. I also suggest increasing the amount of primary that you are using to a dilution of 1:500 and incubating overnight at 4C. Also, you want to ensure that the protein transferred properly to the membrane (check this with Ponceau S) and check that your secondary is working properly. Is the secondary working with other primaries? You may also need to increase the incubation period and concentration of your secondary. I hope this helps. Please contact us again if you need additional assistance.

    Question

    BATCH NUMBER 76164 ORDER NUMBER 61814 DESCRIPTION OF THE PROBLEM No signal or weak signal SAMPLE Cell extracts PRIMARY ANTIBODY ab5986 was the primary antibody. Different dilutions were used form 1:500 to 1:5000. Antibody was diluted in TBS-Tween 5% milk. Incubation time: 1-1h30min Wash step: One rapid was and 3x10 min washes witn TBS-Tween. SECONDARY ANTIBODY Anti-rabbit IgG HRP (Amersham NA934V)was the secondary antibody. Different dilutions were used form 1:20000 to 1:50000. Antibody was diluted in TBS-Tween 5% milk. Incubation time: 1-1h30min Wash step: One rapid was and 3x10 min washes witn TBS-Tween. DETECTION METHOD Pierce Super Signal West Pico POSITIVE AND NEGATIVE CONTROLS USED Yes. Positive control: A431 lysate ab7909. Negative control: cell extract from bacteria. ANTIBODY STORAGE CONDITIONS Stored at +4?C SAMPLE PREPARATION Laemmli buffer has been used to prepare the samples. An equel volume of 2x Laemmli sample buffer was added. The sample buffer was complemented with b-mercaptoethanol. Samples are heated at 95?C for 5 min before loading them in the gel. AMOUNT OF PROTEIN LOADED 50-100 ng of target protein were loaded. ELECTROPHORESIS/GEL CONDITIONS 12% SDS-PAGE. TRANSFER AND BLOCKING CONDITIONS Tris-Glycine-methanol transfer buffer was used for running the gel. Gels were trasnfered for 45 min at 120V. The efficiency of trasnfer was determined by staining the membrane with Ponceau solution. Blocking reagent used was TBS-Tween buffer with 5% milk. HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 15 HAVE YOU RUN A "NO PRIMARY" CONTROL? Yes DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes

    Answer

    I'm sorry to hear you are having a problem with ab5986. I would like to suggest an overnight incubation of the antibody at 4C and maybe try a dilution of 1:300 as well. If you still have problems and your positive control (50ug of lysate per well) clearly shows that the antibody does not work please let me know and please send me an image of your blot and I will arrange for a replacement to be sent to you.

    Question

    As you requested, here is the feedback from the replacement antibody for PERP (ab5986). Please see attached image of WB, obtained with 1 ug/ml of Ab (ab5986), standard conditions, as described in my previous message (regarding use of the other PERP Ab - ab 3945). M=size markers, as indicated; A431 cell lysate, as positive control; 1-4 our samples. Equal total protein loading in all lanes, as demonstrated by GAPDH probing. ab 5986 appears to recognize a band of the expected size, i.e. 21kDa, which was not recognized by the other Ab. However, note that two other bands appear, with the 37 kDa one being the band which appeared strongly immunopositive with the ab 3945, as described previously. Your comments regarding this will be appreciated. Best regards, Luminita.

    Read More
    Answer

    Thank you for getting back to us and providing us some more information about your recent results. We can see on the Western blot image that the 21 kDa band appears nicely, however there are two other non-specific bands as well. It is important to emphasize that ab5986 is a polyclonal antibody and it recognizes different epitopes. Therefore the antibody may recognize other proteins as well which share similar amino acid sequences. We would suggest perhaps reducing the concentration of the primary antibody and applying more stringent washings. Have you tested the secondary antibody alone? We hope this will help.
