靶标

  • 功能

    Induces apoptosis. Isoform BimL is more potent than isoform BimEL. Isoform Bim-alpha1, isoform Bim-alpha2 and isoform Bim-alpha3 induce apoptosis, although less potent than the isoforms BimEL, BimL and BimS. Isoform Bim-gamma induces apoptosis.

  • 组织特异性

    Isoform BimEL, isoform BimL and isoform BimS are the predominant isoforms and are ubiquitously expressed with a tissue-specific variation. Isoform Bim-gamma is most abundantly expressed in small intestine and colon, and in lower levels in spleen, prostate, testis, heart, liver and kidney.

  • 序列相似性

    Belongs to the Bcl-2 family.

  • 结构域

    The BH3 motif is required for Bcl-2 binding and cytotoxicity.

    Question

    Thanks for your reply. I had beta tubulin as the loading control which worked perfectly fine. So I do not think there is a problem with the cell lysate. I stored the antibody at -20 degree celsius afeter alliquoting it in order to avoid repeated freeze/thaw cycles. Unfortunately I do not have access to K562 or A549 whole cell lysates. I did an overnight incubation with the primary antibody at 4 degree celsius. I saw on your website that you also have a monoclonal antibody against BIM ( ab32158). I was wondering if you could send me that antibody ie Anti-BIm antibody (Y36) catalog number ab32158 as a replacement so that I can test it on my samples.

    Question

    Amount of protein loaded was 100ug. Blocked with 5% milk. Primary used 1:1000 in 5% milk. Secondary used 1:2000 in 5% milk. Transfer done using i blot. Washing done 3 times with each wash 15 minutes. Previously I had ordered this antibody in September and it worked a couple of times and then stopped working. I ordered this again last week and keeping exactly the same conditions as before tried it again but it did not work. Samples used were HEK 293, TC32 and SKES cell lysates. The two lot numbers are GR65948-2 and GR85357-1 . I am not sure which lot came last week and which came in September. The one which came in September worked a couple of times while the one which came last week did not work at all. Can you check which of the above lots you sent me in September and send it to me again.

    Answer

    Thank you for taking time to contact us. I am sorry to hear that this antibody is not providing satisfactory results.

    The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality. Would you be able to clarify a few points for me?

    When you say that the antibody wasn't working, was the issue that you were not seeing any bands at all? Have you probed the same membranes for antibodies to other targets (i.e. loading control)?

    Do you have access to K562 or A549 whole cell lysates to use as a positive control?

    Was the primary antibody incubated overnight at 4C?

    How was the antibody stored?

    I took a look at our stocks and unfortunately we do not have any more of the lot you purchased in September (GR85357-1). We only have lot GR65948-2 in stock now.

    In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund. Please let me know how you would like to proceed.

    I hope this information is helpful, and I thank you for your cooperation.

    Question

    The samples were prepared using the attached protocol. 30ug of protein was loaded on the gel. I have attached an improved image of the western blot image with labelled molecular weight markers.

    I blocked the membrane that was incubated with Gadd153 for 1h only.

    Also, the secondary antibodies that I made were fresh but the aliquot I used, was stored at 4 degrees C. Maybe I should try using a fresh aliquot from -20 degrees Celsius. It could be due to the secondary antibody. I will be repeating this procedure tomorrow or sometime this week just to confirm the results.

    I would really appreciate it if you could assist me with any changes that I need to make to my existing protocol to get better results.

    Thank you very much.

    Answer

    Thank you for your reply.


    I am inclined to believe that the issue is with the samples themselves. It is very unusual for 3 different antibodies to detect bands mainly above 100kDa when the expected MW should be around 25kDa. How long are the samples boiled before loading? In reading your protocol, I could only find 1 minute, which is not sufficient. Boiling 5-10 min is advised to completely denature the proteins.


    How do the samples look if you stain the gel with Coomassie? or Ponceau S?

    Furthermore, for at least GADD153, expression must be induced in your samples. Did you do this? Also, ab54740 is only validated for human and may not work with your MEFs. Are you running any sort of a loading control to confirm that the procedure is working with other antibodies?

    I hope this information is helpful. Please do not hesitate to contact me if you have additional questions.

    Question

    I have attached the image of the blot and I have tried to provide you with the description of my experiment. I used Mouse Embryonic Fibroblast (MEF) cells H2AX+/+ and H2AX-/- for my study. I used the same samples to test all three antibodies and cut it to incubate them separately in different antibodies. I have also attached the protocol that I used to perform western blot.

    Thank you very much for your assistance.

    Answer

    Thank you for your reply.

    I was wondering if you would clarify a few additional points for me.


    How were the samples prepared? How much is loaded on the gel?


    What is the molecular weight of each band in the ladder you provided?


    Regarding the WB protocol, each protein may have slightly different requirements, so it is important to consider these when interpreting your results. For example, GADD153 must be induced to be detected by WB with this antibody - how did you treat your cells? Additionally, background is expected with this antibody and a 2hr block with milk is recommended.


    Can you confirm if the secondary antibody you have used with these antibodies is made fresh? Your protocol indicated that your lab does reuse secondary antibody, but we do not recommend it. Have you performed no primary controls to be sure your results are due to the primary antibodies?


    I look forward to your reply so that I may assist you further. I think some modifications to your protocol will help your results with these antibodies. Please do not hesitate to contact me if you have any additional questions.

    Question

    We ordered 3 primary antibodies- Bim, Gadd45a and Gadd153. I used these to test them and my blot shows unspecific binding of antibodies. I was wondering if there is any information that you can provide me with to interpret these results or if there is anyone I could contact?
    Thank you very much.

    Answer

    Thank you for contacting Abcam.


    I am sorry that you have been experiencing difficulties with these antibodies in WB.


    In order to assist you further, I am hoping you can provide some additional details regarding your experiments. Would you please send me a labeled image of your blot, detailed protocol, and sample type and preparation information? Once I have these details, I would be happy to offer some protocol suggestions to improve your results or offer compensation in accordance with our Abpromise.
