title: [Rapid DNA identification using 6+1 STR kit and EX-Q20 electrophoresis].
abstract: OBJECTIVE
  To establish a rapid STR genotyping method for individual identification.
  
  
  METHODS
  Two hundred blood samples from FTA were collected. Equal amount of blood were collected by puncher and analyzed using two methods (6+1 STR kit in combination with EX-Q20 electrophoresis and Sinofiler kit in combination with POP4 electrophoresis). Consuming time and results of two methods were compared.
  
  
  RESULTS
  6+1 STR kit in combination with EX-Q20 electrophoresis method can obtain all genotyping results and be shorter time.
  
  
  CONCLUSIONS
  6+1 STR kit in combination with EX-Q20 electrophoresis method is used to STR genotyping with accurate, reliable results and this new method is potential value in mass personnel investigation and comparison in major criminal cases. It also can raise the work efficiency.
