Fluorescent Colors of the Major Substances That Comprise Atherosclerotic Plaques Excited by Evans Blue Dye (EB).

<p>“A”-imaging = band-pass filter (BPF) 345-nm and band-absorption filter (BAF) 420-nm. “B”-imaging = BPF 470-nm and BAF 515-nm.</p><p>B = blue. G = green. LB = light blue. LY: light yellow. O = orange. P = purple. R = red. RB = reddish-brown. V = violet. W = white. Y = yellow.</p><p>Bold characters = strong fluorescence. Non-bold characters = weak fluorescence. no = no fluorescence.</p><p>This table shows fluorescence colors of the major substances that comprise atherosclerotic plaques excited by Evans blue dye (EB). EB 10⁻⁵M was added to each substance to evoke color fluorescence. A violet fluorescence at “A”-imaging and a reddish-brown fluorescence at “B”-imaging were evoked by adding EB to oxLDL. This combination of fluorescence colors was not evoked in any other known substances that comprising atherosclerotic plaques listed in this table, indicating that this combination is characteristic of only oxLDL.
