Abstract:
OBJECTIVE:To solve the problems of DNA testing in trace sample.
METHODS:Applying original carrier method to detect known trace blood DNA and to compare it with the results obtained by high effective DNA extracting method of Chelex-100.
RESULTS:The carrier method not only could obtain the right STR genotype in the trace blood sample, but also was twice as sensitive as the Chelex-100 method.
CONCLUSION:The carrier method could improve the DNA detection in trace sample. It is easy to operate and is much more valuable in the forensic case analysis.
