Figure 6. ESI-MS full-scan spectra of fsRNA1 (R1, MW, 6048 Da) and its mixtures with 50 µM Kae and Dai.

Figure 6

(A) Mass spectrum of 5 µM RNA alone. RNA solution was prepared by mixing equal volumes of methanol and a 10 µM (150 mM ammonium acetate) solution of RNA; (B) Mass spectrum offsRNA1 with Kae. The solution was prepared by mixing equal volumes of 50 µM methanol solution of Kae and 10 µM (150 mM ammonium acetate) solution of fsRNA1; (C) Mass spectrum offsRNA1 with Dai. The solution was prepared by mixing equal volumes of 50 µM methanol solution of Dai and 10 µM (150 mM ammonium acetate) solution of fsRNA1; (D) Mass spectrum offsRNA1 with 7-hydroxyflavone. The solution was prepared by mixing equal volumes of 80 µM methanol solution of 7-hydroxyflavone and 10 µM (150 mM ammonium acetate) solution of fsRNA1. fsRNA1 alone, and 1∶1, 2∶1, 3∶1, 4∶1, 5∶1, 6∶1 and 7∶1 complexes are indicated.
