For real-time PCR 

The dye (76 mg) was synthesized by using the procedure to make AOAO-2 from 10-(5-carboxypentyl)acridine orange chloride salt (147 mg, 0.35 mmol) and 2,2â² oxybis(ethyl-amine) dihydrochloride (25 mg, 0.14 mmol). <br>

Preparation of AOAO-2 (Dye No. 7 of Table 1)

Et<sub>3</sub>N (0.15 mL, 1.05 mmol) and TSTU (320 mg, 1.05 mmol) were added to a suspension of 10-(5-carboxypentyl)acridine orange chloride salt (438 mg, 1.03 mmol) in DMF (5 mL) at room temperature. The mixture was stirred at room temperature for 15 minutes, followed by the addition of Et<sub>3</sub>N (0.1 mL) and 3,3â²-diamino-N-methyldipropylamine (50 mg, 0.344 mmol). After the mixture was stirred at room temperature overnight, EtOAc (20 mL) was added to precipitate the product. The crude product was re-dissolved in DMF and precipitated out again with EtOAc. The solid (250 mg) was separated by centrifugation. <br>
