Figure 3From: Potassium bicarbonate and D-ribose effects on A72 canine and HTB-126 human cancer cell line proliferation in vitroUV/VIS absorbance spectra of MTT salt with and without K:D-Rib solution. A, black dashed line: MTT - SDS UV/VIS spectrum; coloured solid lines: MTT - K:D-Rib interaction product UV/VIS spectra after solubilization obtained subtracting the MTT- SDS spectrum from raw data. Different K:D-Rib concentrations, 1.5 mM, 5 mM, 10 mM, 15 mM and 75 mM (inset) were used. B, black line: MTT salt UV/VIS spectrum; red line: formazan salt after solubilization (ROCHE data sheet).Back to article page
