Objective:
To study the extracting and genotyping method of sweat latent fingerprint samples involved in cases.
Method:
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.
Conclusion:
It is very important to find and extract sweat latent fingerprint samples properly for STR genotyping.
