The lab works on a method for acquiring sequence data from single nucleic acid molecules. The approach involves a fluorescence resonance energy transfer assay (FRET) based on molecules involved in protein biosynthesis. The fluorescence signal is acquired from single molecules using a fluorescence correlation spectroscope in several configurations, including measurements in solution and on surfaces. The project's goals are to: (i) perform site-directed labeling with a fluorescent dye and quencher; (ii) optimize the FRET assay; (iii) construct a synthetic template and demonstrate the performance of the system on this template; (iv) investigate nanostructures capable of enhancing fluorescence; (v) study the behavior of single molecules in the system; and (vi) demonstrate the capability of the system to acquire high volumes of sequence data. The method once fully developed will allow fast analyses of many types of nucleic acids. The project is funded by the NIH program on the "Revolutionary Genome Sequencing Technologies - the $1000 Genome".

In addition, Dr. Mandecki's research interests include the mechanisms of frameshifting in ribosomal translation, phage display, protein structure and function, and innovative techniques in nucleic acid and protein analysis.
