Technical platform
Advances in sequencing, chemistry, and bioinformatics
The clonoSEQ Assay is differentiated from other NGS assays by groundbreaking advances in chemistry and proprietary bioinformatics.[1,2] Together, these discoveries translate into unique advantages for clinicians and patients.
Next-generation sequencing
NGS is an advance in DNA sequencing technology that enables simultaneous identification of millions of unique B-cell and T-cell receptors from a single sample.[1,2,5]
Because of its scale, high speed, and low cost, NGS makes it possible and clinically practical to characterize a tremendous breadth of genetic information at high throughput.[1,2,6]
NGS enables differentiation of very small numbers of remaining malignant cells against a background of millions of normal cells.[1,2]
Advantages in chemistry
clonoSEQ leverages proprietary innovations to solve the problem of PCR amplification bias.[1,2]
The solution is a library of synthetic molecules that enables clonoSEQ to analyze the entire immune repertoire, every time the test is used.[1,2]
That’s why clonoSEQ not only tracks sequences that are identified at diagnosis as markers of disease at diagnosis, but can also detect newly emerging clonal sequences over time.[7]
Advances in bioinformatics
The outputs of NGS are millions of raw sequencing reads. To distill all this data into MRD results that are clinically meaningful and easy to understand, clonoSEQ uses a series of proprietary algorithms that were developed based on the analysis of billions of sequences.[1,2]
