Bioactive Pigments of Monascus purpureus: Identification and Characterization

Journal of Food and Pharmaceutical Sciences
Monascus purpureus is a filamentous fungus that has long been recognized as one of the main producers of natural pigments. These pigments, including yellow (ankaflavin, monascin), orange (rubropunctatin, monascorubrin), and red (rubropunctamine ...

Pigment Melanin: Pattern for Iris Recognition

, 2009
Recognition of iris based on Visible Light (VL) imaging is a difficult problem because of the light reflection from the cornea. Nonetheless, pigment melanin provides a rich feature source in VL, unavailable in Near-Infrared (NIR) imaging.

Isolation of pigment cell specific genes in the sea urchin embryo by differential macroarray screening [PDF]

, 2003
New secondary mesenchyme specific genes, expressed exclusively in pigment cells, were isolated from sea urchin embryos using a differential screening of a macroarray cDNA library. The comparison was performed between mRNA populations of embryos having an

Identification of Pigment Cell Antigens Defined by Vitiligo Antibodies

Journal of Investigative Dermatology, 1992
Patients with vitiligo have circulating antibodies to pigment cells. To characterize this response further and to identify the antigens defined by vitiligo antibodies, sera of 23 patients with vitiligo and 22 patients with unrelated conditions were analyzed by immunoprecipitation and SDS-PAGE analysis of 125I-labeled cell antigens on pigment and ...
