    The poly(A)-binding protein (PABP), which is found complexed to the 3-prime poly(A) tail of eukaryotic mRNA, is required for poly(A) shortening and translation initiation. Grange et al. (1987) isolated a melanoma cell cDNA encoding human PABP. The predicted 633-amino acid protein contains 4 repeats of an approximately 80-amino acid unit in its N-terminal half. The authors found that this repeat region is highly conserved between human and yeast PABP and is sufficient for poly(A) binding. In vitro translation of the human PABP cDNA yielded a protein with an apparent molecular mass of 73 kD by SDS-PAGE. Northern blot analysis indicated that PABP is expressed as a 2.9-kb mRNA in human melanoma cells. Gorlach et al. (1994) noted that each of the 4 repeats of PABP is a ribonucleoprotein (RNP) consensus sequence RNA-binding domain. They determined that PABP has a pI of approximately 10.3 and is a very abundant, stable protein. Immunofluorescence studies of mammalian cells indicated that PABP is located exclusively in the cytoplasm. However, using both indirect immunofluorescence and tagging of PABP1 by fusion to the green fluorescent protein (GFP), Afonina et al. (1998) demonstrated that PABP1 shuttles between the nucleus and cytoplasm. PABP1 accumulated in the nucleus when transcription was inhibited, suggesting that active transcription is required for nuclear export of PABP1.

    Question

    Dear concerning,
    A user would like to use Anti-PABP antibody [10E10] (ab6125) on follicular fluids by ELISA. Could you please suggest a dilution rate for the antibody to use ELISA? Additionally, is PABP peptide (ab23710) suitable to use with PABP antibody [10E10] (ab6125) as standard?

    Asked on Aug 29 2012

    Answer

    Thank you for contacting us.

    There is not a specific concentration recommended for the use of this antibody in ELISA. Optimisation is required with different dilutions in order to assess the best one for your particular conditions. We can however suggest a good starting point to begin with, for purified antibodies tested in ELISA this corresponds to 0.1ug/ml.

    Regarding the suitability of ab23710 to be used as standard with the antibody, I am afraid I cannot assure the antibody will recognize it, as its epitope has not been mapped, and we have not tested this pair in house.

    However, the peptide ab23710 has been used to raise another Anti-PABP antibody:

    Answer

    Thank you again for your calls and for your patience while we have looked into your enquiry. I apologize again for the delay in getting this information for you.

    My contact at the lab confirms that this antibody has an IgG2b isotype. I've looked online and there are other antibodies with the 10E10 clone number (though one is to a different protein target, Raptor). I'm not sure how to explain the discrepancy with the PABP antibody listed as an IgG1 isotype from other vendors, though most companies seem tolist this as an IgG2b clone.

    I am sorry that we don'thavemore of an explain regarding this discrepancy, but if you have any further questions or if there is anything else that we can do for you, please let me know and I'll be happy to help.

    Question

    I have purchased the anti-PABP antibody (ab6125) and used it successfully in western blot experiments. Recently I have attempted to use it in antibody inhibition experiments with RNA and have found that the RNA is being degraded during the experiment. I was under the impression that these antibodies were highly purified and therefore should be free of ribonucleases. It would be greatly appreciated if you have knowledge about the purity of the antibodies generated (if it is lot dependent) and if abcam or any other company guarantees their antibodies to be nuclease free.

    Asked on Jul 30 2007

    Answer

    Thank you for your enquiry. I have received information from our laboratory. The purification steps are not done aseptically (it's impossible) and so whilst I guess there could be some bacterially derived endonuclease, I think it unlikely as all our columns are stored in ethanol and all the tubing etc washed extensively before each run. Moreover, even if there were any endonucleases present, I would be surprised if they bound non specifically to protein G and so I wouldn't expect to see them in the end product. This is substantiated by the fact that we don't see any low (12-14Kd) MW bands in the preps when we run SDS-PAGE gels. Whilst we filter sterilize the preps prior to despatch, I guess if the antibody has subsequently been handled non-aseptically at any point, this could introduce bacteria which could produce endonuclease, however I think it unlikely. I hope this information will be useful to you. Should you require any further information, please do not hesitate to contact me.

    At Abcam, we have one centralized database to hold all of our product information, so that everything we know about this antibody is on this datasheet. We are unable to supply the epitope sequence as this is deemed commercially sensitive information. However it may be of help to you to view the references cited at the base of the data sheet.
