The gentle collection and lysis chemistry of the alcohol-free iSWAB buffer allows for recovery of double-stranded, large fragment DNA similar to the genomic DNA generated from blood, making it suitable for complex genomics downstream arrays such as microarrays and Next Generation Sequencing. Other non-invasive collection methods often utilize alcohol and can produce short DNA fragments limiting their usability to basic genotyping applications.
The iSWAB-DNA device allows for the collection and stabilization of DNA at the point of collection without the need for swab inclusion. Typical yields of between 5-30μg of DNA with <1% bacterial contamination can be achieved. DNA collection kit for humans that can capture samples producing high yields of double-stranded, long fragmented DNA from buccal cells using traditional swabs.

Performance:
High Genomic DNA Yield - Due to the efficient Mawi proprietary stabilizing and bacteriostatic lysis storage buffer in the tube, iSWAB DNA achieves high genomic DNA yields.
Low Bacterial Genomic DNA Contamination - iSWAB was able to achieve low bacterial genomic DNA contamination compare to the traditional methods. Primers specific for the 16S ribosomal RNA gene were used as a simple method to obtain relative quantification of bacterial DNA.
