摘要
A guanine derivative with a covalently linked nitroxide spin label has been devised. The spin label was incorporated into oligodeoxynucleotides by post-synthetic modification. The local environment of a variety of G-rich DNA is detectable by ESR using this spin probe. (C) 2004 Elsevier Ltd. All rights reserved.
