FAQ-303
303 - Can I use my own lysis buffer with the DNeasy Blood & Tissue or QIAamp DNA Mini Kit?
If you have optimized the lysis conditions for a specific sample type, you can lyse the sample in your lysis buffer, and follow the Supplementary Protocol 'Purification of total DNA from crude lysates using the DNeasy Blood & Tissue Kit' (DY15), or the corresponding protocol in the Appendix of the QIAamp DNA Mini Kit and QIAamp DNA Blood Mini Kit Handbook.

DNeasy Blood & Tissue Kits
DNeasy Blood & Tissue Kits quickly extract DNA using a silica-based, phenol- and chloroform-free process in spin-column and 96-well-plate formats. For most samples, direct lysis with proteinase K eliminates the need for mechanical disruption, reducing hands-on time. Tailored protocols for specific samples ensure consistent extraction of high-quality DNA, perfect for life science, genotyping, and veterinary pathogen research. Kits can be automated on QIAcube Connect.
For a more sustainable alternative, the QIAwave DNA Blood & Tissue Kit, reduces plastic and cardboard usage by up to 62% and 58%, respectively. The kit includes waste tubes made from 100% recycled plastic, which can be reused throughout the procedure. QIAwave buffers are concentrated, decreasing plastic use in each bottle by up to 90%. Despite visual differences, the QIAwave Kit remains as user-friendly as the standard kit, with identical chemistry and performance. Note: Sterile glass bottles are required for buffer reconstitution.
In partnership with My Green Lab, we've assessed the environmental impact of the DNeasy Blood & Tissue Kit (50/250) and the QIAwave DNA Blood & Tissue Kit (50/250). My Green Lab ACT environmental impact factor labels aim to assess and rate products based on various sustainability criteria, including:
Manufacturing
Responsible chemical management
Sustainable content within products and packaging materials
Disposal of the packaging at the end of life
Products are scored from 1 to 10 except for energy and water consumption, which are scored as 1 point per kWh or gallon, respectively. A low score means a lower environmental impact – see figures “DNeasy Blood & Tissue Kit and QIAwave DNA Blood & Tissue Kit ACT environmental impact factor labels“ US ( 50/ 250), EU ( 50/ 250) and UK ( 50/ 250)."
QIAamp DNA Kits
QIAamp DNA Kits provide silica-membrane-based nucleic acid purification from tissues, swabs, CSF, blood, body fluids or washed cells from urine. In addition, genomic and mitochondrial DNA can be purified from small amounts of fresh or frozen blood, tissue and dried blood spots. Mechanical homogenization is not required as the tissues are lysed enzymatically. DNA purification from 1–12 samples can be automated on the QIAcube Connect using the dedicated QIAamp DNA Mini QIAcube Kit. Purification of DNA using the QIAamp DNA Micro Kit and QIAamp DNA Mini Kit is also automatable on the QIAcube Connect.
QIAamp DNA Mini standard protocols can also be executed using the TRACKMAN Connected system.
