benefits Icon

Many non-invasive collection methods often utilize alcohol, which can cause the sample to produce short DNA fragments, limiting its ability to be used in basic genotyping applications. Other sample collection methods utilize a dry transport which does not stabilize the sample at the point of collection, causing bacteria to overgrow and jeopardize the yield of DNA. iSWAB™-DNA is an alcohol-free, gentle lysis technology allowing for the 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.

Product detail


  • Simple, fast and convenient sample collection: Self-collection or assisted collection with high simplicity and ease in less than 5 minutes
  • High nucleic acid recovery: Up to 15µg (ISWAB™-DNA-250) of double-stranded, long fragment DNA for downstream applications including microarray and NGS
  • Low bacterial genomic DNA contamination: Achieve less than 3% bacterial genomic DNA contamination
  • Swab-free sample transport: Decrease sample processing time without compromising sample integrity
  • Suitable for all population segments including infants, toddlers, and elderly
  • Efficient traceability and storage purposes: LIMS compatible unique barcodes included on each iSWAB device

Product Description

Each iSWAB™-DNA-250 collection device consists of a collection tube that is pre-filled with 600 µL of the nontoxic iSWAB™-DNA-250 buffer and fitted with a proprietary insert. The insert is designed to optimize the release of specimens collected with swabs into the gentle lytic buffer, creating a minimal footprint and allowing for swab-free transport of specimens. Self-collection or assisted collection can be achieved in less than 5 minutes and is suitable for all population segments including infants, toddlers, and elderlies. iSWAB™-DNA-250 is pre-barcoded for traceability and storage, and is easy to process via manual and automated applications. The device is human gDNA and PCR inhibitor free and collected samples are stable at room temperature (15-30 °C) for 60 days.

Intended Use

The iSWAB™-DNA-250 collection device is a DNA sample collection device for the collection, stabilization, concentration, transport, and storage of DNA samples. It is a non-invasive swab-based sampling applicator and is intended to be used for sample collection of buccal cells. The DNA collection kit for humans can capture samples producing high yields of double-stranded, long fragmented DNA between 5-15μg (iSWAB™-DNA-250) with <3% bacterial contamination using traditional sampling swabs.

Indication for Use (from IFU)

The iSWAB™-DNA-250 collection device is intended for the collection of double-stranded, large-fragment DNA at the point of collection without the need for swab inclusion. The gentle collection and lysis chemistry of the nontoxic iSWAB™-DNA-250 buffer allows for the recovery of DNA comparable to the genomic DNA generated from blood, making it suitable for complex genomics downstream assays such as microarrays, NGS, and Sanger sequencing. The device can be used for ambient temperature (15-30 °C) transport and storage. Ideal for: paternity testing, genealogy, ancestry, population genomics, cancer research, HLA typing, and epidemiology.

Storage and Stability

“Pre-collection: 3 years from date of manufacture between 15-30° C.
Transport temperature, post-collection: 15-30° C.
Sample stability and storage, post-collection: 60 days real time and 3 years accelerated time; if longer storage time is required, collected samples can be stored at -20 to -80° C.”
