Introducing trASO™ for pharmacokinetic bioanalysis of antisense oligonucleotides
trASO™ offers quantification Antisense Oligonucleotide Therapies (ASOs) directly in biological samples such as blood serum. Using Nanovery's patented Nucleic Acid Nanorobotics (NANs) platform, trASO™ comes as a reagent, offering an enzyme-free and isothermal assay format designed for simplicity and reliability.
trASO™ can be easily tailored to support a range of ADME, biodistribution and pharmacokinetic (PK) studies in bioanalysis, with the flexibility to accommodate various ASO patterns (such as Antagomir, Gapmer, ssDNA), chemical modifications, chemical conjugates and sample types.

Chemical modifications
ASOs are chemically modified to boost their stability, uptake and target affinity. These modifications, including additional moieties for stability, targeting, and biodistribution, also interfere with the efficiency of enzymatic processes in qPCR, leading to inconsistencies in quantification.
trASO™ assay is based on our proprietary NAN technology. It is distinctively enzyme-free and relies on nucleic acid hybridisation and strand displacement reactions, which makes it excel at consistently detecting ASOs. Read more about our technology (here).

Proven performance of trASO™ according to ICH-M10 guidelines
Our DNA nanorobots demonstrate remarkable compatibility with chemical modifications, offering robust detection and precise quantification of antisense oligonucleotides. We validate the ASO detection and quantification assay in line with ICH-M10 guidelines to guarantee high levels of accuracy, precision, and selectivity across biological matrices. You can find our full collection of validation data here.
Compatibility with chemical modifications in antisense therapies
The results below illustrate the robust detection capabilities of NANs across four sample types: 1) DNA, 2) RNA, and ASOs with 3) OMe, and 4) MOE modifications. These assays demonstrate excellent linear responses, enabling precise quantification within the low picomolar range. Small error bars indicate high accuracy, and the simplicity of data analysis highlights the practical efficacy of our technology in various bioanalytical settings.
