[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.
