Figure 7. GK-peptide ribose assays.

GK- peptide (50 mg/ml) in 100 µL of 500 µM sodium phosphate buffer containing 0.02% NaN₃ at pH 7.4 was mixed with 0.1 ml of 120 mg/ml ribose in 0.5 M sodium phosphate buffer in the absence or the presence of the 200 µM MF and 20 mM PM and incubated for 14 days at 37°C. The fluorescence of the mixture was read at 340 nm excitation and 430 nm emission wavelength. Results are the mean ±S.D (n = 3), p<0.001.
