Leveraging our technology for low-quality RNA samples, CD Genomics provides RNA sequencing services for Formalin-Fixed Paraffin-Embedded (FFPE) tissues to help you discover critical information in preserved samples. Utilizing an optimized high-throughput sequencing process, our FFPE RNA-Seq service enables gene expression studies on small sample amounts and reliable detection of low-expressed genes with accuracy and integrity of transcriptome data, which can be applied in biomarker discovery, disease diagnostic research, precision therapy development, and more.
Transcriptome sequencing is increasingly applied in pre-clinical and clinical research to provide important information on gene expression regulation and mechanism, as well as allele-specific expression profiling, fusion detection, mutation detection, and therapy selection. A variety of technologies have been developed for the detection of clinical or preclinical samples, such as blood transcriptome sequencing, biofluid RNA sequencing, and other RNA sequencing methods for fresh frozen tissues. The FFPE process is currently the standardized method for long-term preservation of samples, and is commonly used to preserve a large resource of clinically diseased and normal tissue samples. However, FFPE samples are often precious and have a long shelf life, suffering from low RNA volume and high degradation, which make it difficult to use standard RNA sequencing techniques. CD Genomics has established a next generation sequencing based solution dedicated to low-quality RNA samples and small sample amounts, including FFPE tissue RNA-seq services, by optimized experimental manipulation methods and bioinformatic analysis techniques. Our services can focus on both coding RNA regions (mRNA) and total RNA, and can meet the needs of a diverse range of medical research biological samples.
