The most common question: GeneLokr™ or truGnom®?
PRESERVE NOW, EXTRACT LATER
GeneLokr™
An ambient fixative that keeps cells and nucleic acids intact.
- Long ambient transport and storage: DNA 10–12 months, RNA 5 months at 15–25°C.
- NGS, PCR, RT-PCR, qPCR and microarrays.
- Tissue, blood, invertebrates, hair, swabs, plants, fungi, faecal samples, soil and eDNA.
LYSE NOW, EXTRACT IMMEDIATELY
truGnom®
An active lysis and stabilisation medium that releases and protects nucleic acids on contact.
- Direct-to-extraction metagenomic and genomic workflows.
- High-throughput isolation, metagenomic profiling and molecular diagnostics.
- All sample types except blood.
| Feature | GeneLokr™ (ambient fixative) | truGnom® (active lysis & preservation medium) |
|---|---|---|
| Primary mechanism | Passive preservation: locks cellular architecture and nucleic acids intact at room temperature. | Active lysis: lyses cells on contact while stabilising the released nucleic acids. |
| Sample state after collection | Intact cells and specimens preserved in a liquid matrix. | Lysate: cellular contents fully released and stabilised in solution. |
| Next step in the lab | Extract after transport (extraction is required). | Go straight to extraction (cells are already lysed). |
| Ideal workflow | Long-term ambient transport and storage (DNA 10–12 months, RNA 5 months at 15–25°C), or when intact structural recovery or multi-step processing is wanted. | Rapid, direct-to-extraction metagenomic and genomic workflows where immediate cell-wall and membrane disruption is critical. |
| Downstream focus | NGS, PCR, RT-PCR, qPCR, microarrays. | High-throughput nucleic acid isolation, metagenomic profiling and molecular diagnostics. |
| Sample types | Tissue, blood, invertebrates, hair and swabs from animals and humans; plant leaves, fungi, faecal samples, soil and environmental DNA (eDNA). Stabilises both DNA and RNA at ambient temperature. | All sample types except blood. |
| Quick rule | Preserve now, extract later. | Lyse now, extract immediately. |

Questions about choosing
What is the difference between GeneLokr™ and truGnom®?
GeneLokr™ is an ambient fixative that keeps cells and nucleic acids intact for long transport and storage, so you extract later. truGnom® is an active lysis and stabilisation medium that lyses cells on contact, so you go straight to extraction. Choose GeneLokr™ to preserve now and extract later; choose truGnom® to lyse now and extract immediately.
Which product should I use for blood?
Use BloodGnom™ for whole-blood DNA and RNA, cfDNA or cfRNA. GeneLokr™ also supports blood when you want it kept intact for extraction later. truGnom® is for all sample types except blood.
How do BiomLife® and BiomLife® Pro differ?
BiomLife® covers microbiome work, culture and DNA, PCR, NGS and WGS for up to 3 weeks at 15–25°C. BiomLife® Pro does all of that and adds multi-omics (metatranscriptomics, proteomics, metabolomics) and up to 2 years of ambient storage.
Which medium lets me skip DNA/RNA extraction?
ALCHESIS™ MTM. After a brief heat step and a quick spin, the clear supernatant goes straight into LAMP, PCR, TMA or NASBA.
