[PCR-based STR genotyping of sweat latent fingerprint samples involved in cases].
OBJECTIVE
To study the extracting and genotyping method of sweat latent fingerprint samples involved in cases.


METHODS
Chlex 100 extraction method was used to extract DNA. STR loci were typed after PCR amplification by Profiler Plus kit.


RESULTS
All the sweat latent fingerprint samples involved in cases obtained reliable results of STR genotyping.


CONCLUSIONS
It is very important to find and extract sweat latent fingerprint samples properly for STR genotyping.
