    靶标

    • 功能

      Required for DNA replication. Plays a role in the rescue of stalled replication forks and checkpoint control. Binds double-stranded DNA breaks and nicks as well as single-stranded DNA. Recruits the SWI/SNF chromatin remodeling complex to E2F1-responsive promoters. Down-regulates E2F1 activity and inhibits E2F1-dependent apoptosis during G1/S transition and after DNA damage. Induces a large increase in the kinase activity of ATR.
    • 组织特异性

      Highly expressed in heart, brain, placenta, lung and kidney.
    • 序列相似性

      Contains 8 BRCT domains.
    • 翻译后修饰

      Phosphorylated on serine and threonine residues in response to X-ray irradiation.
      Ubiquitinated and degraded by the proteasome. X-ray irradiation reduces ubiquitination.
    • 细胞定位

      Nucleus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle pole. Chromosome. Detected on unpaired autosomes in meiotic prophase cells. Detected on X and Y chromosomes during later stages of prophase. Colocalizes with ATR and H2AFX at unsynapsed chromosome cores during prophase (By similarity). Has a uniform nuclear distribution during G phase. Colocalizes with BRCA1 at stalled replication forks during S phase. In mitotic cells it colocalizes with BRCA1 at spindle poles and centrosomes during metaphase and anaphase. Detected in discrete foci together with PML and numerous DNA repair enzymes after DNA damage by alkylating agents, UV or gamma irradiation. Localizes to sites of DNA damage in a H2AX- independent manner.

      2) Abcam order reference number or product batch number #1109783

      3) Description of the problem we identify an interaction between our protein of study and TopBP1 but there is another interaction more specific then TopBP1 recognized by TopBP1 antibody also in input of hela cell lines extract. The IP to TopBP1 is ok but I want to know what is the other band. The MW of Claspin is 150Kda but it migrates at 250Kda because of its iso-electric point and Chk1 is 55Kda

      4) Sample preparation:

      Type of sample whole Hela cell lysates

      Lysis buffer: Hepes-NaOH 50mM ph 7,5 , NaCl 150mM, 1% glicerol, 1% Triton X100, MgCl2 1,5mM, EGTA 5mM

      Protease inhibitors:protease inhibitor cocktail 78410 as recipe

      Phosphatase inhibitors phosphatase inhibitor cocktail 1861277 as recipe

      Amount of Lysate IPed ug or number of cells 2mg of lysate for IP

      Lysate precleared with matrix : yes

      Positive control whole Hela cell lysates 50ug

      Negative control No IP only matrix


      5) IP antibody:

      Amount/concentration or dilution used 2ug of antibody for IP

      Conjugation:

      Antibody noncovalently bound to matrix before incubation with lysate sample? NO

      Antibody noncovalently bound to matrix after incubation with lysate sample? YES

      Antibody covalently bound to matrix - please describe briefly? NO

      We used to pre-clear the cell lysates for 1h at 40C on roacking with 30ul of beads then pellet it for 5’ at 2000rpm 40C, collect the supernatant and put it to contct with antibodies O.N. Next day we used 20ul of beads/IP to bound the immunocomplex

      Antibody-lysate incubation time: Over night

      Incubation temperature 40C on roacking

      6) IP Matrix (e. beads):

      Type of matrix Protein G sepharose 4 fast flow GE Healthcare 17-0618-01

      Amount of matrix 20ul

      7) Washing after antibody-lysate incubation:

      Buffer: : Hepes-NaOH 50mM ph 7,5 , NaCl 150mM, 1% glicerol, 1% Triton X100, MgCl2 1,5mM, EGTA 5mM

      Number of washes 5

      8) IP analysis:

      Verification method: e.g reprobe in western blotting NO

      Describe verification method briefly:

      We used ECL Plus Western Blotting Detection Reagents Amersham

      OR if Western blotting reprobe performed please indicate the following:

      Reducing agent Bme

      Boiling for ≥5 min? yes

      Protein loaded ug/lane or cells/lane 50ug for input

      Percentage of gel 10%

      Type of membrane Amersham Hybond ECL Nitrocellulose Membrane

      Protein transfer verified: YES, Ponceau

      Blocking agent and concentration 5% milk in TBS+1% Tween

      Blocking time 1h

      Blocking temperature RT

      Primary antibody (If more than one was used, describe in “additional notes”) :TopBP1 ab2402

      Concentration or dilution 1:1000

      Diluent buffer 5% milk in TBS+1% Tween

      Incubation time Oven night

      Incubation temperature: 40C

      Secondary antibody:

      Species: Goat

      Reacts against: Rabbit

      Concentration or dilution 1:3000

      Diluent buffer 5% milk in TBS+1% Tween

      Incubation time 45’

      Incubation temperature: RT

      Fluorochrome or enzyme conjugate: horseradish peroxidase conjugated

      Washing after primary and secondary antibodies:

      Buffer TBS+1% Tween

      Number of washes 5

      Detection method

      Was the method successfully used to detect protein from non-IPed samples? Yes this methods detect the band of TopBP1 and another with smaller MW

      Document attachment: Attaching images of your blot is strongly recommended and can greatly speed up our investigation of your problem.

      Asked on Jul 03 2012

      Answer

      Thank you for your enquiry regardingab2402 and for taking the time to provide some useful details of the experiments. I am very sorry to hear that you are having problems with this antibody.

      We regret to inform you that we do not know the identity of the band in question. We only know the identity for the target band TopBP1.

      Does the detection system work fine? Have you used it successfully with another primary antibody? Have you run a no primary - only secondary antibody - control to see if any of the non-specific bands are due to the secondary or not? If you have not done yet, I would advise you to check it.

      I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.

      Question

      Dear Abcam,
      I have a technical problem with a TopBP1 ab2402. I study the involment of novel protein in DNA damage response. I use a IP technic to identify if my protein of interest is a TopBP1 partner. I think that the interaction is ok but in the film there is another interaction more specific then with TopBP1. Your antibody recognized this other band with equal specificity to TopBP1. I know that your antibody can cross-react with CLASPIN (150 Kda) or CHK1 (55 Kda) but the MW is enought different. I enclose you also a photo of film with a detailed informations.
      I can hope you can help me in resolving this problem
      Best regards

      I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

      In order to better understand the problem, I would like to send you a questionnaire with some questions about the protocol used, as well as the order details. All this information is crucial to help us understand the possible causes of the problem. Any images are highly appreciated.

      Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. If no suggestions can be made to the protocol, and the antibody was purchased within the last 6 months, it is covered by our Abpromise guarantee, and therefore I can offer you a free of charge replacement or a credit note for it.

      I look forward to receiving your reply. Please do not hesitate to contact us if you need any more advice or information.
