Sample Collection

Sample collection is a critical preanalytical step for any application. Investigations on the influence of preanalytical considerations such as sample collection and storage have underscored their importance in determining the validity and usefulness of data for downstream analyses.1,2,3 In order to obtain the most clinically relevant information, it is imperative to ensure that there is minimal sample loss, consistency in collection, and preservation of sampleintegrity. Roche Sequencing Solutions provides essential tools, from simple collection tubes to sophisticated tissue dissection systems, which enable you to efficiently capture challenging tumor samples such as formalin-fixed paraffin-embedded tissue (FFPET) or cell-free DNA (cfDNA).

AVENIO Millisect System

Optimized to fit easily into a variety of clinical workflow configurations, the automated, high-performance AVENIO Millisect System provides precise and consistent recovery of FFPE tissue regions of interest with maximum efficiency. This can help you extract the most clinically relevant information from every sample.

Cell-Free DNA Collection Tube

Providing specimen stability, safety and durability, the Cell-Free DNA Collection Tube is specially formulated for the collection, stabilization and transportation of whole blood specimens, and for preservation of nucleated cells to enable analysis of cell-free DNA. Available both in RUO* and CE-IVD** formats.

*Research Use Only. Notforuseindiagnosticprocedures.
**Available for countries that accept CE-Mark.
