DNA genotyping of oral epithelial cells by laser capture microdissection / 法医学杂志

OBJECTIVE@#The STR genotypping of trace oral epithelial cells which are microdissected by laser capture microdissection system (LCM) is explored.@*METHODS@#The oral epithelial cells are microdissected using a low-power infrared laser by VERITAS Microdissection Instrument. STR loci of Profiler Plus are detected by multiplex PCR procesures.@*RESULTS@#DNA genotyping of 7-8 oral epithelial cells are succeeded, and DNA genotyping of 3-4 oral epithelial cells are failed.@*CONCLUSION@#It is viable in genotyping of trace oral epithelial cells by Laser Capture Microdissection as a new technology of seperating single cell.
