Figure 4. FL detection of various collagens and other proteins by present 3,4-DHPAA assay method.

Figure 4

(a) FL signals obtained from 10 nM collagenous and non-collagenous proteins, and biological specimens. (b) FL images from (i) H2O, (ii) human collagen-I and (iii) cheek tissue measured for a. Each bar is the mean ± SD of three repeated experiments. Total protein levels of 33.6 and 220 μg as mean value in the cheek tissue and HeLa cell lysates were determined by a commercial kit, respectively.
