Repeated extraction of DNA from FTA cards

Extraction of DNA using magnetic bead based techniques on automated DNA extraction instruments provides a fast, reliable and reproducible method for DNA extraction from various matrices. However, the yield of extracted DNA from FTA-cards is typically low. Here, we demonstrate that it is possible to repeatedly extract DNA from the processed FTA-disk. The method increases the yield from the nanogram range to the microgram range. 2011 Elsevier Ireland Ltd. All rights reserved. * Corresponding author. Tel.: +45 28756311; fax: +45 35326270.
