FTA Cards (GE Healthcare) have been used for more than 4 years in Denmark for the
collection of buccal cells as reference samples in crime cases. Semi-automated protocols for
STR typing of DNA on punches of FTA Cards are routinely used. In average, full STR profiles
were generated from approximately 95% of the FTA Cards with a standard punching
protocol, while partial or no STR profile were obtained from 5% of the samples. Here, the

FTA Cards (GE Healthcare) have been used for more than 4 years in Denmark for the collection of buccal cells as reference samples in crime cases. Semi-automated protocols for STR typing of DNA on punches of FTA Cards are routinely used. In average, full STR profiles were generated from approximately 95% of the FTA Cards with a standard punching protocol, while partial or no STR profile were obtained from 5% of the samples. Here, the Qiagen BioRobot® EZ1 Workstation (Qiagen) and the EZ1 DNA Investigator Kit (Qiagen) was used to extract DNA from 29 FTA Cards from which a complete STR profile was not generated with the standard punching protocol. All 29 samples were successfully typed with the AmpFℓSTR® Identifiler™ PCR Amplification Kit (Applied Biosystems) and with the SNPforID 49plex SNP assay. The lowest amount of DNA that resulted in complete STR and SNP profiles was 80pg. The STR and SNP profiles were identical to those generated from another sample collected from each of the 29 individuals.
