FFPE RNA Sequencing Services

Profiling of Archival Tissue Samples

FFPE RNA-seq is a powerful tool for gene expression profiling of archival tissue samples. The FFPE RNA sequencing services can be used for bulk, single cell, and spatial profiling.  At SeqMatic, FFPE RNA-seq is used in studies related to the progression of disease and to identify potential biomarkers for diagnosis and treatment.

Service Features

Research Approach –

FFPE can be used for bulk total RNA, single cell RNA, and VISIUM spatial RNA profiling.

Stringent Quality Controls –

SeqMatic qualifies RNA with a TapeStation Electropherogram for each total RNA sample submitted. A TapeStation analysis includes a RNA Integrity Number (RIN) and DV200 for each sample, which establishes relative length as a measure of RNA quality. Results are shared for review and approval prior to proceeding to library preparation.

High-Quality design considerations for read depth –

SeqMatic has recommendations for different research approaches:

  • For FFPE Bulk Total RNA-seq we recommend 50 to 60M reads per sample.
  • For 10x Genomics Flex FFPE we recommend 10K reads per cell (per 10x Genomics protocol)
  • For 10x Genomics Visium spatial transcriptomics we recommend 25K read pairs per spot covered

Higher and lower read depths are available depending on project needs

 

Preliminary Sequencing –

After library preparation, libraries are pooled in equal volumes and the final pool is quantified by Agilent TapeStation and checked via preliminary sequencing (MiSeq). Libraries are then normalized and re-pooled based on the read number from the preliminary sequencing dataset.

Histopathology –

Full service histopathology laboratory available.

World-class validation standard & practices –

SeqMatic is equipped to ensure accurate, repeatable and reproducible results. SeqMatic’s quality program has been audited and approved as part of becoming a Clinical Laboratory Improvement Amendments (CLIA) and College of American Pathologists (CAP) certified sequencing facility. Our CLIA quality program requires the use of well-defined protocols to maintain the consistency and reproducibility of our NGS workflows. Thus, the samples will be processed in a CLIA environment.

Custom assay services –

Our highly personalized sequencing services can be adapted to almost any (high and/or low throughput) sequencing workflow required by our customers so that we optimize the quality and quantity of data output.
