          <datacite:description xml:lang="ja" descriptionType="Abstract">DNA中の二本鎖切断(DSB)に対するアスコルビン酸(AA)およびDMSOの保護効果を、蛍光顕微鏡による巨大DNA(T4 DNA; 166kbp)の単分子観察によって評価した。凍結／解凍の状態に対して3つの異なる形態の放射源、可視光、γ線、および超音波の環境下にさらした。1‐プロパノールと2‐プロパノールの間で異なる効果が表れた。ゲノムDNA分子の高次構造の変化は、1−プロパノールを用いると、長軸長が濃度60％で最小を示し、次にアルコール含有量の増加と共に増加する傾向があることを見出した。一方、2−プロパノールを用いると、長軸長はアルコール含有量の増加と共にほぼ単調な減少を示した。</datacite:description>
          <datacite:description xml:lang="en" descriptionType="Abstract">The protective effect of ascorbic acid (AA) and DMSO against double-strand breaks (DSBs) in DNA was evaluated by single-molecule observation of giant DNA (T4 DNA; 166kbp) through fluorescence microscopy. Samples were exposed to three different forms of radiation: visible light, γ-ray, and ultrasound or freeze/thawing. The change of the higher-order structure of genomic DNA molecules in the presence of alcohols by use of single DNA observation with fluorescence microscopy, by focusing our attention to unveil the different effect between 1-propanol and 2-propanol.</datacite:description>
