Custom DNA Sequencing Solutions

Custom DNA Sequencing Solutions

We offer the development of custom RUO DNA sequencing solutions for retrospective use tailored to clients exact requirements.

When a biomarker assay is required for trial enrichment, or a patient treatment decision will be made based on the result, assays must be run under CLIA / GLP. Not all biomarker assays that take place in the clinical trial setting will result in patient treatment decisions; those that are pharmacodynamic (PD) biomarkers or assays for research use only purposes (RUO) do not require the same level of validation and are typically run retrospectively in batches as the trial progresses.

Although the validation requirements are less stringent, we develop and process these assays under the same quality management system and with the same processes and protocols for robust delivery.

Almac Additional Benefits for DNA Sequencing Solutions

Flexible Extraction Protocols: Almac offer both high-quality single DNA extractions and a dual RNA / DNA extraction protocol for our DNA-Sequencing solutions. Dual extraction facilitates simultaneous generation of RNA-Seq data and DNA-Seq data from a single sample, conserving valuable sample material.

Customisable Analysis & Reporting: Data analysis and reporting is performed using Almac customised bioinformatics pipelines implemented on DNAnexus, a global leader in biomedical informatics and data management. DNAnexus is a cloud-based NGS solution which ensures scalability and security of project data. A significant benefit of utilising DNAnexus within this offering is the flexibility of workflow optimisation and the ability to customise bespoke pipelines.
