RNA and Biosample Stabilisation

Home/Other Products & Services/RNA and Biosample Stabilisation

Rapid Labs are proud to be the global supplier for RNAssist.

RNAssist specialises in next generation tissue fixation and biomolecule stabilisation. Their reagents are compatible with all biological sample types and consist of two products, depending on your application: genoPHIX™ and vivoPHIX™.

RNAssist reagents offer the following benefits:

Biomolecule Stabilisation
Long term stabilisation of RNA, DNA, proteins and phosphoproteins

Cell & Tissue Fixation
Conserves cellular morphology of fresh & frozen tissue, compatible with GFP, IF, IHC, ISH and RNAscope imaging

Inactivates viruses, bacteria and yeast*
Allows work in lower biosecurity settings to enable safe, easy transportation of sensitive samples

Economical Advantages
Store and ship at room temperature, eliminating the need for expensive cold-chain transport

Tissue Dissociation (with vivoPHIX™)
Suitable for single-cell multi-omic analysis

See what our customers are saying about RNAssist:

‘RNAssist is an amazing technology with important applications for us. I haven’t been so excited about something in quite some time.’
– Canadian Food Inspection Agency

‘The FISH signals were better in RNAssist for the three probes I have tested. The big advantage is that we can avoid using the chemical fume hood with RNAssist.
– University of Cambridge

‘RNAssist is a valid alternative fixative to both preserve tissue morphology and RNA integrity and it is recommended when alcohol-based methods cannot be used to post-fix the tissue’
– European Institute of Oncology

‘I am convinced that we have very good inactivation of the virus’ – Pasteur Institute

‘The RNA quality is very high. The quality was higher than the corresponding methanol fixed tumour’
– University of Oxford

‘Single cell libraries are better with RNAssist. The RNAssist sample is much purer and have more reads per cell. It’s working amazingly for my project’ – Sanger Institute

‘This has made clear (as expected) that we need an alternative RNA stabilisation reagent to the one we were using’
– Sanger Institute

*Every virus tested so far with RNAssist have been inactivated. Inactivation must be tested internally by the end user. Please contact us to review the full list of viruses and bacteria that have been effectively inactivated with RNAssist.
