  • Target

    • Relevance

      DNA Gyrase A belongs to the topoisomerase gyrA/parC subunit family. DNA gyrase negatively supercoils closed circular double stranded DNA in an ATP dependent manner and also catalyzes the interconversion of other topological isomers of double stranded DNA rings, including catenanes and knotted rings. It is made up of two chains. The A chain is responsible for DNA breakage and rejoining; the B chain catalyzes ATP hydrolysis. The enzyme forms an A2B2 tetramer. When the enzyme transiently cleaves DNA a phosphotyrosine bond is formed between the gyrA and DNA.

      Thank you for contacting us.

      Most of our antibodies are stable at -20C for up to five years. For short term storage we recommend storing at 4C. It is also important to aliquot them in order to minimize damage due to freezing and thawing.

      If after following these recommendations you are still experiencing problems with the antibody, please let us know, and I’ll be happy to follow this quality issue up.

      All of our products are covered by our Abpromise guarantee; which ensures that you can trust our products, and they should work in the tested species and applications stated on the datasheet, or we will offer a replacement, credit, or refund, if reported within 6 months of purchase.

      Please let me know how the antibody performs, and do not hesitate to contact us if it does not do it as expected.
