Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Validation experiments using multiple biological sample types demonstrated stable genomic DNA purification with purity ratios typically A260/280 around 1.7–1.9, indicating high-quality genomic DNA suitable for downstream molecular analysis workflows.

Extraction experiments across different tissue samples showed reproducible DNA yields with variation between replicate extractions typically below 10%, demonstrating stable purification performance across multiple sample types.

Purified genomic DNA produced clear high-molecular-weight bands in agarose gel electrophoresis and supported successful PCR amplification of target gene fragments, confirming compatibility with common molecular biology applications such as PCR amplification and genotyping analysis.

Comparative testing against commonly used commercial genomic DNA purification systems showed comparable DNA purity and recovery performance, supporting reliable DNA preparation for routine laboratory workflows.

Genomic DNA purified using the BioString^TM Universal DNA Kit is suitable for a wide range of molecular biology and molecular diagnostics research workflows, including:

• PCR amplification
• Genotyping analysis
• HLA typing studies
• Molecular diagnostics research
• Population genetics studies
• Sample preparation for sequencing workflows
• Biobanking sample processing
