Sample preservation solutions for the problems researchers actually face
Ruhvenile® is a specialist manufacturer of specimen preservation and molecular sample-preparation technologies. Find your problem below and see the proprietary technology that solves it. Every product is discovered, developed and manufactured in India.
How do I ship microbiome samples without dry ice?
Use BiomLife®. It keeps stool, soil, environmental and tissue samples intact for up to 3 weeks at 15–25°C and revives live bacteria, fungi and phages. It supports microbiome studies in cancer, AMR, sewage, oral, skin, soil, HIV, tuberculosis, STI and preterm birth.
How do I keep live microbes and multi-omics from the same tube?
Use BiomLife® Pro. One tube gives living microbes plus DNA, RNA, protein and metabolite protection, with up to 2 years at 15–25°C (predicted).
Why do Gram-positive bacteria and fungi disappear from my metagenomic data?
This is lysis bias: saturated salt fixatives harden tough cell walls so extraction kits cannot open them. GeneLokr™ conditions cell walls without premature lysis, and truGnom® lyses cells at collection.
How do I stop RNA degrading during field transport?
Use GeneLokr™. It irreversibly deactivates RNases and DNases, keeping RNA stable for over 5 months and DNA for 10–12 months at 15–25°C.
How do I preserve tissue biopsies for single-cell RNA-seq?
Use sCellTisu™. It keeps biopsies ready for scRNA-seq, snRNA-seq and spatial transcriptomics for 72 hours at 15–25°C with no ice and no formalin. Research use only.
How do I collect blood for DNA, RNA, cfDNA or cfRNA without a cold chain?
Use BloodGnom™. Pre-filled tubes keep whole-blood DNA and RNA for up to 15 days, cfDNA for 15–30 days and cfRNA for 7–15 days at 2–25°C.
How do I transport swabs for viral PCR without a cold chain?
Use ViroGnom™ VTM for PCR and sequencing, or ViroStabl™ UTM when you need viral culture as well. ViroStabl™ keeps samples for up to 120 hours at 2–25°C.
How can I run culture and PCR from one urine sample?
Use UroStabl™. It is boric acid and formate free, keeps pathogens viable for 5–7 days at 15–25°C and supports culture and PCR or NGS from the same urine.
How can I do a PAP smear and HPV test from one cervical sample?
Use the CytoStabl™ LBC Kit. It keeps cervical cells for 30+ days at room temperature and supports cytology and HPV testing. Research use only.
How do I skip DNA extraction in field diagnostics?
Use ALCHESIS™ MTM. It lyses and stabilises raw samples for direct LAMP, PCR, NASBA or TMA, with no spin-column step and 7–30+ days of ambient stability.
