Figure Lengend Snippet: Fluorescence spectrum of [Co(phen) 2 (Cl)(H 2 O)] + in the absence and presence of different concentration of salmon sperm DNA. [Co(phen) 2 (Cl)(H 2 O)] + concentration: 1.00 × 10 -4 mol L -1 ; DNA concentration (mol L -1 ): (1): 0; (2): 3.12 × 10 -4 ; (3): 4.68 × 10 -4 ; (4): 5.46 × 10 -4 .

Article Snippet: Salmon sperm DNA (10 mg mL -1 , A 260 /A 280 >1.8) were purchased from Huashun Biological Engineering Company (Shanghai, China) with the concentration being determined by the ultraviolet absorption at 260 nm (ε = 6600 L mol -1 cm -1 ).

Techniques: Fluorescence, Concentration Assay
