Quantitative RNA Sequencing

Specialty DNA Sequencing

SeqLL offers quantitative RNA and specialty DNA sequencing services utilizing True Single Molecule Sequencing technology. Our services can complement mainstream sequencing approaches to help you address your toughest challenges, add additional rigor or explore poorly characterized, rare transcripts and mutations. Our goal is to enable the advancement of science by further refining what is currently understood about biology and disease.

Our testing services are fully customizable to your research needs and particular challenges. Our expert team will design a sequencing protocol that optimizes the breadth of data collected with turn-around time and cost. We can provide raw data as well as full-service bioinformatics support and summary reports. We excel in partnering with our clients to not just collect, but truly understand data generated.

At SeqLL we understand how important turn-around time is to our customers. Since True Single Molecule Sequencing utilizes a streamlined pre-sequencing process relative to standard approaches, we can generate raw data quickly.

Services

DRS™

SeqLL’s DRS™ genetic testing and mapping services is an important step forward in the RNA Sequencing world. For the first time, researchers can explore the RNA transcriptome directly as it exists In-vivo, with no conversion to cDNA or amplification required. DRS™ service captures polyadenylated RNA directly without conversion to cDNA. Sequence RNA directly from the flow cell surface.

tSMS ™ FORMALIN FIXED PARAFFIN EMBEDDED (FFPE)

SeqLL’s tSMS™ services is uniquely suited to analyze damaged or fragmented nucleic acids from formalin fixed paraffin embedded samples and other difficult sources. Sample degradation during processing or storage can be a challenge for other NGS systems.

Micro RNA Sequencing

True Single Molecule Sequencing is ideally suited to miRNA and other short RNA species.

CUSTOM SEQUENCING, MAPPING & TESTING

Bring us your most challenging RNA sequencing projects. Our experienced team will work with you to design a custom program to generate the publication quality data you require. The unique research and development capabilities of the tSMS allow us to succeed where others have failed.

RNA - SEQ

Transcriptome studies require quantitative sequencing in order to determine levels of gene expression for a large number of transcripts in a given sample. In many sample types, abundant but uninteresting transcripts, such as ribosomal RNA or housekeeping gene transcripts can make up the majority of the sequencing reads and can necessitate greater depth of coverage to generate enough reads of lower abundance transcripts.

 

In addition to the standard reverse transcriptase method using random hexamers or dT primers, SeqLL offers a not-so-random (NSR) primer approach to selectively remove high abundance transcripts from the sample during the reverse transcription step of our cDNA-based RNA-Seq protocol. Taking advantage of the high tolerance of reverse transcriptase to mis-prime, it is possible to use as few as 40 pseudo-random (PS) reverse transcription primers to decrease the rate of undesirable abundant sequences within a library without affecting the overall transcriptome diversity.

PS primers are simple to design and can be used to deplete specific undesirable RNAs simultaneously, thus creating a flexible tool for enriching transcriptome libraries for rare transcript sequences. Let our team work with you to create a NSR primer approach specific for your application.
