    Imaging Collagen in Intact Viable Healthy and Atherosclerotic Arteries Using Fluorescently Labeled CNA35 and Two-Photon Laser Scanning Microscopy by Remco T.A. Megens, Mirjam G.A. oude Egbrink, Jack P.M. Cleutjens, Marijke J.E. Kuijpers, Paul H.M. Schiffers, Maarten Merkx, Dick W. Slaaf, Marc A.M.J. van Zandvoort

    Published 2007-07-01
    “…CNA35 conjugated with fluorescent Oregon Green 488 (CNA35/OG488) was administered ex vivo to mounted viable muscular (uterine), elastic (carotid), and atherosclerotic (carotid) arteries and fresh arterial rings. Two-photon microscopy was used for imaging. CNA35/OG488 labeling in healthy elastic arteries was compared with collagen type I, III, and IV antibody labeling in histologic sections. …”
