The BioStringTM Fast Blood DNA Kit was validated using 200 µL whole blood samples on a MagMix 32 automated extraction system. The extracted DNA showed A260/280 values mainly around 1.78–1.90 and A260/230 values mainly around 1.7–2.0, indicating reliable DNA purity for automated blood DNA extraction workflows.
Workflow robustness was evaluated under different heating conditions. Both heated and non-heated sample-well conditions produced recoverable DNA with clear gel bands, supporting flexible use in automated extraction programs.
The effect of lysis buffer volume was also tested using 200 µL blood input. Different Buffer MLA volumes produced usable DNA, and the validation suggested that 1.5× lysis buffer volume supported strong A260/230 performance. The use of 500 µL Buffer MLA in the sample well supports flexible blood input volumes from approximately 100–400 µL.
Proteinase K input was further evaluated from 0–20 µL. The extraction workflow was not highly sensitive to Proteinase K amount, and acceptable DNA could still be recovered without Proteinase K under the tested conditions. However, adding Proteinase K improved yield and purity, with 5–10 µL providing high-quality DNA in the tested workflow.
