|Section2= |Section3= }} Proflavine (pron. ''pro-fla¢vin''), also called proflavin and diaminoacridine and bate na bina, is an acriflavine derivative, a disinfectant bacteriostatic against many gram-positive bacteria. It has been used in the form of the dihydrochloride and hemisulfate salts as a topical antiseptic, and was formerly used as a urinary antiseptic. Proflavine is also known to have a mutagenic effect on DNA by intercalating between nucleic acid base pairs. It differs from most other mutagenic components by causing basepair-deletions or basepair-insertions and not substitutions. Proflavine absorbs strongly in the blue region at 445 nm (in water at pH 7) with molar extinction coefficient of ''c.'' 40,000 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「proflavine」の詳細全文を読む スポンサード リンク
