Triplicate 1 L water samples were filtered using five different 47 mm diameter membrane filters (PVDF, PES, GFF, PCTE, and NC) and DNA was extracted from triplicates of each filter-type using three widely-used extraction methods (the DNeasy Blood and Tissue kit, the MoBio PowerWater DNA Isolation kit, and standard phenol/chloroform methods) resulting in 45 individual eDNA samples prepared with 15 workflow combinations.

References: ASTM International. Sterile Filters. Sterile filtration is commonly employed for microbial removal and plays a pivotal role in assuring final product sterility. Where sterility will be claimed, regulatory agencies worldwide require that the sterilizing-grade filter (s) be integrity tested to ensure filter performance is verified prior to and after filter use.

DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. The sterile filter should be positioned at the final stage of the delivery system and at the “point of use” as a final barrier to remove all viable organisms which may be harboured in the CO 2 delivery system. There are a range of filters available which are marketed as providing “sterile” filtration for gas. For the sterile filtration Sterile applications, whether liquid or air, usually require a sterile-grade liquid filter rated at 0.2 micron.

2010-05-01 · In this paper we have described the use of an automated microscale multiwell filtration technique for examining the behaviour of DNA vectors during sterile filtration. The experimental results showed that the recorded behaviours obtained in the multiwell filtration design and the conventional unstirred normal flow membrane system were comparable. …or PCR primers especially for GC rich DNA sequences and thus increase amplification. DMSO, Sterile Filtered is prepared by filter sterilizing DMSO through 0.2 micron filter. DMSO, Sterile Filtered is suitable for cell culture and tissue culture work that require elimination of all potential… Working Mechanism of Filtration Sterilization. Filters work by physically trapping particles larger than the pore size and by retaining somewhat smaller particles via electrostatic attraction of the particles to the filters.

This eliminates contaminants that may cloud your results. Optimally, you should use a DNA Free swab that is tested and certified to be DNA free. When it comes to selecting the right sterile swab, you have some choices.
