Abstract: 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.
Key Words: sweat latent fingerprints; DNA examination; STR genotyping |
