    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 the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

靶标

  • 功能

    Oligomeric Apaf-1 mediates the cytochrome c-dependent autocatalytic activation of pro-caspase-9 (Apaf-3), leading to the activation of caspase-3 and apoptosis. This activation requires ATP. Isoform 6 is less effective in inducing apoptosis.

  • 组织特异性

    Ubiquitous. Highest levels of expression in adult spleen and peripheral blood leukocytes, and in fetal brain, kidney and lung. Isoform 1 is expressed in heart, kidney and liver.

  • 序列相似性

    Contains 1 CARD domain.
    Contains 1 NB-ARC domain.
    Contains 13 WD repeats.

  • 结构域

    The CARD domain mediates interaction with APIP.

    Question

    Hi,
    Thanks for your reply. I have used the same type of samples ( of course different preparation) which I have used for ab2001. I have tried in male Wistar rat brain homogenate and PC12 cell lysate as well. I have used it for western blot analysis, with caspse 3, I tried dilutions up to 1:500. Blocking with BSA, 4 degree incubation with primary antibody. I could not get signals with any of the variations. My western is working well as I am getting signals for house keeping genes in the same blot. If I have to provide further details please let me know.
    Best,

    Answer

    Thank you for your message and for kindly confirming these details.

    According to our records, ab59388 was ordered in October which is past our 6 month guarantee period. However, reviewing the details, I can make an exception and provide a replacement or credit note for ab59388 in this case.

    With regards to the other free of charge order for ab2001, order ref 1083546, I apologise for the delay. I would appreciate if you could confirm if you would like the replacement for ab59388 aswell, then I can add this to the same order and arrange for this to be shipped tomorrow (Wednesday) and it will take about 6 days to get to you.

    I am sorry we do not ship antibodies on dry ice in order to avoid an extra freeze thaw cycle. They are shipped on ice, and with careful monitoring of customer feedback, we are not aware that this causes any problems with product quality.

    Thank you for your time and cooperation. I look forward to hearing from you.

    Question

    Product code: 2001
    Lot number: GR 26336-2
    Inquiry: Hello, I had contacted the technical help desk earlier for my problem with immunoblot. I tried the suggestions and I got bands, in one blot i gt band around 130 kDa, with some non specific bands but in subsequent blot i got single band around (range between 55-75 kDa). I checked with the literature and i got variation in band size of Apaf1. Please provide me information of the variation of Apaf 1 size. I am looking for Apaf1 in apoptotic brain tissues. your help would be highly appreciated. best,

    Answer

    Thank you for providing this further information.

    I appreciate your cooperation and understand your concerns. It is regrettable the results have not been succesful. I have traced your previous corresopndence and reveiwed this case.

    With regards to the band sizes expected for PAF1 protein in WB, the Uniprot protein database lists 6 isoforms of different sizes:

    http://www.uniprot.org/uniprot/O14727
    Isform 1 142 kDa
    Isoform 2 141 Kda
    Isoform 3 136 Kda
    Isoform 4 137 kDa
    Isoform 5 133 kDa
    Isoform 6 37 kDa

    Unfortunately, none of these would match the bands at 55 - 75 kDa that you are seeing. I can confirm this antibody has not specifically been tested on brain samples in WB and regrettably, I am having difficulty confirming which isoforms are known to be expressed in the brain with a literature search. I could just find the following article: http://www.pnas.org/content/104/52/20820.full that mentions normal brain has little Apaf-1 and tumors have a higher level, but unfortunately nothing specific to which isoforms are in the brain.

    Could you confirm if any samples from other tissue have been included as a positive control? I can suggest this would be highly beneficial in this case.

    In order to help with our investigation of this case before deciding how to proceed, I would appreciate if you are able to provide more detail as requested in the previous email. This information will also be helpful to our quality monitoring.

    1. Please confirm the Abcam order reference number and date of purchase

    2. For the secondary antibody, I can suggest an anti-rabbit secondary would be required to detect the rabbit polyclonal primary. An anti-goat would not detect rabbit polyclonal. If the correct secondary is being used, I can sugest it is also worth considering if the current vial is working well with other primary antibodies?.

    3. Try a higher concentration of antibody to increase the signal. Try 1:1000. Incubate overnight 4oC.

    4. Could you confirm which lysis buffer was used? I can recommend to lyse the cells in RIPA lysis buffer if this has not already been tried, before adding SDS loading buffer such as Laemmli to reduce and denature the samples. This should provide a more suitable protein preparation.

    I would appreciate if you could also provide an image, including molecular weight markers, which would help us to assess the results.

    I will be pleased to provide a free of charge replacmenet or credit note if the antibody is not working with the suggestions provided.

    Thank you for your time and cooperation. We look forward to receiving the requested information and results from the positive control.
