Abstract

original image

DNA-gestützte Affinitätsmarkierung: Die Charakterisierung der Wechselwirkungen zwischen einer niedermolekularen Verbindung (SM) und einem Protein ist eine wichtige Aufgabe in der chemischen Biologie und Wirkstoff-Forschung. DNA-programmierte Photoaffinitätsmarkierung wird als neue Methode vorgestellt (siehe Bild). Durch die Kodierung mit DNA und den Templateffekt ist das parallele Markieren des Proteins mit verschiedenen Sonden möglich.
