Frederick, Jeanne M.; Thulin, Craig; Bernstein, Paul S. | Identification and characterization of a Pi isoform of glutathione S-transferase (GSTP1) as a zeaxanthin-binding protein in the macula of the human eye | Uptake, metabolism, and stabilization of xanthophyll carotenoids in the retina are thought to be mediated by specific xanthophyll-binding proteins (XBPs). A membrane-associated XBP was purified from human macula using ion-exchange chromatography followed by gel-exclusion chromatography. Two-dimensio... | Circular Dichroism; Isoelectric Focusing; Macula Lutea; Xanthophylls | 2004 |

Bernstein, Paul S.; Gellermann, Werner | Nonmydriatic fluorescence-based quantitative imaging of human macular pigment distributions. | We have developed a CCD-camera-based nonmydriatic instrument that detects fluorescence from retinal lipofuscin chromophores ("autofluorescence") as a means to indirectly quantify and spatially image the distribution of macular pigment (MP). The lipofuscin fluorescence intensity is reduced at all ret... | Cytology; Sensitivity and Specificity | 2006-10 |
