[DNA genotyping of oral epithelial cells by laser capture microdissection].

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.
