Formalin-fixed, parrafin-embedded (FFPE) samples are the most common and available world-wide specimen type for human disease diagnosis. As such, they represent a very rich and valuable reservoir of relevant DNA and RNA sequence information. However, the process used to create these samples results in highly fragmented and chemically damaged nucleic acid that present unique challenges for NGS applicants.
Omega Bio-tek has extensive expertise in the successful extraction and nucleic acid purification of FFPE samples and even manufactures an extraction kit specifically optimized for this very difficult sample type. Omega Bioservices translates this expertise into on-site service capability and consistently provides this extraction method for many customer, specifically on FFPE samples for NGS applications.
Sequencing is perfomed on an Illumina HiSeq 2500 utilizing V4 chemistry or the MiSeq with V3 chemistry. These chemistries allow you to receive the maximum value for your samples. Results delivered via secure cloud drive or external hard drives are available.

Quality of data
At Omega Bioservices, we understand that the quality of the DNA going into next generation sequencing is directly related to the quality of the sequence data coming out. That is why quality metrics are captured at vital points during our process:
- Post extraction: DNA is analyzed to ensure it is of sufficient fragment size and quantity for optimal library preparation chemistries.
- Post library preparation: Fragment size and quantity is again checked to ensure optimal loading onto the Illumina flow cell.
- Post capture: For exome sequencing service, the fragment size and quantity of the capture pool is again checked for optimal flow cell loading.
- NGS run: Careful monitoring of the quality (Q) scores along with cluster densities, percentage of reads passing filter, number of reads generated, and average length of reads.
This constant and consistent quality monitoring effort result in the very best product possible delivered to the customer.
As next generation sequencing methodologies continue to improve and evolve, they can generate expansive datasets that address complex biological questions. Existing bioinformatics programs may not be able to adequately address the nuanced aspects of your problem set or simply do not offer the level of analysis that you need.
If you are in need of analysis advice on you NGS dataset, or need direct analysis assistance, Omega Bioservices has a network of specialized bioinformatics providers with the expert knowledge and computational resources to help you achieve your data analysis objectives. We can also help in the experimental design at the very beginning of your project to maximize the value of your data.
