Target

  • Function
    Component of the HBO1 complex which has a histone H4-specific acetyltransferase activity, a reduced activity toward histone H3 and is responsible for the bulk of histone H4 acetylation in vivo. Through chromatin acetylation it may function in DNA replication. May inhibit tumor progression by modulating the transcriptional output of signaling pathways which regulate cell proliferation. Can suppress brain tumor angiogenesis through transcriptional repression of RELA/NFKB3 target genes when complexed with RELA. May also specifically suppress loss of contact inhibition elicited by activated oncogenes such as MYC. Represses hypoxia inducible factor's (HIF) activity by interacting with HIF prolyl hydroxylase 2 (EGLN1).
  • Sequence similarities
    Belongs to the ING family.
    Contains 1 PHD-type zinc finger.
  • Cellular localization

Images

  • Anti-p29 ING4 polyclonal antibody detects ING4 protein by western blot. This antibody was used at 1.0 ug/ml to detect ING4 (lane 2) present in a U2OS whole cell lysate over expressing the protein. A control lysate (lane 3) shows no background staining. Comparison to MW markers (lane 1) indicates detection of a single band at ~29 kDa corresponding to ING4.

    A 4-20% Tris-glycine gradient gel was used to separate the protein by SDS-PAGE under reducing conditions. The protein was transferred to nitrocellulose using standard methods. After blocking using 5% non-fat dry milk in PBS, the membrane was probed with the primary antibody overnight at 4° C followed by washes and reaction with a 1:20,000 dilution of IRDye800 conjugated Rabbit anti Goat IgG [H&L] for 45 min at room temperature. LICOR's Odyssey® Infrared Imaging System was used to scan and process the image. Other detection systems will yield similar results.

Answer

Thank you for your enquiry and for submitting your protocol details. I am sorry to hear that you have been having difficulties with this antibody. I have read your technical questionaire in association with your blot images and I would appreciate it if you could address the following questions; 1. Please can you confirm that the samples that you are running are tissue samples. 2. Can you tell me how you are preparing the tissue lysates; the details in the questionaire were confusing. What buffer are you using. 3. In an earlier email you mentioned that "The 29KD lane in the PVDF when is dealt with ponceau red". Does this meant that the marker lane in the blots that you emailed me has a molecular weight marker of 29KDa. 4. Can you tell me the percentage of Tween in the TBST that you are using. You mention "TBS-t=1/4". Can you please tell me the percentage of Tween 20 that you have been using. I ask because there is noticeable noise in the immunoblots that you have emailed me. 5. Can you tell me whether you have been able to obtain good results using this approach with an alternative antibody but the same tissue lysate. This would confirm that the approach, reagents, secondary antibody, transfer conditions etc that you are using are ok. I appreciate your patience and look forward to hearing from you.

Answer

Thank you for your enquiry. I'm glad to hear that the antibody is giving good preliminary results in IHC. I hope that you will submit an Abreview with your results. Regarding the Western blot, the recommended starting dilution range is between 1/500 to 1/3000. It may be that you must use the antibody at a higher concentration (I generally recommend starting at 1/500 for polyclonals as well) to visualize the bands. It would be great if you could let me know further details of your protocol so we could see what kind of samples, how much protein, etc. The questionnaire for this is at the following link: https://www.abcam.com/index.html?section=western&pageconfig=technical&intAbID=3714&mode=questionaire This antibody was used at 1.0 µg/ml to detect ING4 present in a U2OS whole cell lysate over expressing the protein. A single band was detected at ~29 kDa corresponding to ING4. A 4-20% TRISglycine gradient gel was used to separate the protein by SDS-PAGE under reducing conditions. The protein was transferred to nitrocellulose using standard methods. After blocking using 5% non-fat dry milk in PBS, the membrane was probed with the primary antibody overnight at 4° C followed by washes and reaction with a 1:20,000 dilution of IRDye800 conjugated Rabbit-anti-Goat IgG [H&L] for 45 min at room temperature. LICOR's Odyssey® Infrared Imaging System was used to scan and process the image. Other detection systems will yield similar results. The HRP-conjugated secondary recommended for this antibody is ab6741, Rabbit polyclonal to Goat IgG. I have added a new Western blot image to the datasheet (it may take a couple of hours for it to show up online). Unfortunately I am unable to attach the images to this email, but I have provided a link directly to the datasheet at the bottom of this email. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for your enquiry. We would like to emphasize the fact that this is a Fast track antibody and it has only been assayed by ELISA against 0.1µg of the immunizing peptide. It has not been tested for Western blot analysis at all. We have read through the completed questionnaire; however we still need the following information. Unfortunately, the details you have provided are not enough for us to be able to identify the source of the problem. What type of samples your customer has tested (species, cells, tissue, recombinant protein etc)? How was the cell lysate prepared? How much protein was loaded onto the gel? At what dilution the antibody was tested? Has the customer tested the detection system? How about the protein transfer? What did he/she use as positive control? We look forward to hearing from you soon.

Answer

At the bottom of the online datasheet for ab3714 there is a list of compatible secondary antibodies and so yes, ab6742 is an appropriate choice.
