Concluding Remarks
The data reported demonstrates the GlobalFiler® PCR amplification system followed by
CE detection in a 3500 Genetic Analyzer generates high quality, reproducible, precise,
accurate, and sensitive profiling STR data, even from sub-nanogram amounts of genomic
DNA template and also in the presence of powerful PCR inhibitors co-extracted with
DNA from a high variety of forensic samples including the following DNA sources: blood,
semen & saliva stains, hair, muscle, liver, bone and teeth.
The GlobalFiler® system provides equivalent overall performance to previous forensic STR
PCR kits, but with enhanced discrimination power for a better match efficiency that
would reduce the chance of adventitious matches during DNA data exchange among
national DNA databases.
The use of GlobalFiler® kit would be also very beneficial to improve discrimination power
of DNA analysis not only in criminal DNA databases, but also in many other forensic
applications of autosomal STR profiling including missing person identification, disaster
victim identification, mass grave investigations and kinship analysis.

  • 27. Concluding Remarks The data reported demonstrates the GlobalFiler® PCR amplification system followed by CE detection in a 3500 Genetic Analyzer generates high quality, reproducible, precise, accurate, and sensitive profiling STR data, even from sub-nanogram amounts of genomic DNA template and also in the presence of powerful PCR inhibitors co-extracted with DNA from a high variety of forensic samples including the following DNA sources: blood, semen & saliva stains, hair, muscle, liver, bone and teeth. The GlobalFiler® system provides equivalent overall performance to previous forensic STR PCR kits, but with enhanced discrimination power for a better match efficiency that would reduce the chance of adventitious matches during DNA data exchange among national DNA databases. The use of GlobalFiler® kit would be also very beneficial to improve discrimination power of DNA analysis not only in criminal DNA databases, but also in many other forensic applications of autosomal STR profiling including missing person identification, disaster victim identification, mass grave investigations and kinship analysis.
