    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

    Z-DNA is one of the many possible double helical structures of DNA. It is a left-handed double helical structure in which the double helix winds to the left in a zig-zag pattern (instead of to the right, like the more common B-DNA form). Z-DNA is thought to be one of three biologically active double helical structures along with A- and B-DNA.

Question

Thanks for your reply.
I appreciate that information regarding the antibody is proprietary, I am not seeking disclosure of their methods. However, I still need to know if they carried out any testing on the antigen to establish its purity. In other words, can the supplier state that only Z-DNA was injected?

Read More
Answer

Having checked with the lab, we can confirm that a preparation of Z-DNA (i.e. left-handed DNA) of sufficient purity has been injected.
I am sorry that we are unable to provide more details, but I hope this information is nevertheless helpful to you. We aim to provide as much information as possible to customers, so I am sorry that this has not been possible on this occasion. Should you have any further questions, please do not hesitate to contact us.

Question

Please provide details on the method and the quality control used in the synthesis of the brominated DNA used to raise this antibody. Is the starting material removed from the bromination product prior to further use? Are DNA breakdown products removed from the bromination products? Is the bromination done under controlled conditions? What temperature is the DNA bromination carried out under?

Read More
Answer

Thank you for contacting us and your patience.
Unfortunately, the antigen used to produce this product was made a few years ago in a laboratory at a private university. Most information regarding this antibody is propriety, however, I can tell you the following: Z-DNA antibody was raised in sheep using brominated poly-(DG-DC)-left handed DNA (Z-DNA) complexed to methylated BSA as the immunogen.
I hope this information is still helpful for you. Please do not hesitate to contact us if you need any more advice or information.

Question

I have purchased Z-DNA antibody(ab2079) and have two questions: - What is the immunogen for this antibody - Are you aware of a DNA sequence that could be used as a positive control for immuprecipitation Many thanks in advance

Read More
Answer

Thank you for your inquiry. The lab where this antibody is produced informed me that, unfortunately, at this time they do not have a specific DNA sequence that could be used as a positive control for immunoprecipitation. We will update the on-line datasheet for this product as soon as we receive additional data. We apologize for any inconvenience this may cause.

Thank you for contacting us. Z-DNA antibody was raised in sheep using brominated poly-(DG-DC)-left handed DNA (Z-DNA) complexed to methylated BSA as the immunogen. I asked the lab about a recommended positive control. I will contact you again as soon as I receive this information.

Question

I have purchased Z-DNA antibody(ab2079), and then crosslinked it to Z-DNA using formaldehyde. Would you give me some suggestuions about how to shear the cross-linked DNA to 500-1000 base pairs ? By the way, the sonication treatment is not allowed in the current situation.

Read More
Answer

Thank you for your enquiry. Your question is indeed an interesting one. The two most commonly used techniques for the preparation of chromatin are sonication and a mild micrococcal nuclease digestion. They can both be employed for use in cross linked chromatin. However, the nuclease digestion of chromatin relies on the fact that the digestion of DNA is obscured by the association of the DNA with the nucleosome template and therefore the chromatin is preferentially digested into mono, di- and tri-nucleosomes etc. However, given that you are digesting free Z-DNA this is not applicable as either MNase (or DNAse I or II) will fully digest the DNA to completion. The only thing that will provide you with suitable resolution is a restriction enzyme. This has been adopted in the context of chromatin in the following publication using a mild PstI digestion; Kang SH, Vieira K, Bungert J. 2002 Combining chromatin immunoprecipitation and DNA footprinting: a novel method to analyze protein-DNA interactions in vivo. Nucleic Acids Res. May 15;30(10) I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Question

I have ordered the Z-DNA antibody(ab2079),but I don't know the effective final concentration.Do you know the binding plateau of the antibody? Thanks.

Read More
Answer

Thank you for your enquiry. There is a reference on the datasheet for this antibody(ab2079) which as far as I can tell recommends a dilution of 1:10 for ISH. European Journal of Histochemistry. 2004 48 (1) 49-56. Z-DNA a new in situ marker for transcription. I hope this reference will be helpful. If you are using the antibody for IP, then I would recommend using 10-500 µg cell lysate plus 0.5-5 µg of antibody. The precise amount will need to be optimised for your particular application. I hope this is helpful. Please do not hesitate to contact us again if you require more assistance.
