Figure 3From: Iron specificity of a biosensor based on fluorescent pyoverdin immobilized in sol-gel glassFluorescence and absorbance titrations. A) Fluorescence titration of purified pyoverdin (3 replicates). Data points indicate the fluorescence 10 min. after each iron (III) addition. (ex/em = 390/452 nm) B) Absorbance titration of purified pyoverdin (2 replicates). Data points indicate the absorbance 10 min. after each iron (III) addition.Back to article page
