BTSeq™ Standard Service

Up to 20kb or more, NGS-based sequencing without the need of primer walking


"Celemics is able to significantly lower the Library Prep processing and overall analysis costs by developing our own proprietary BTSeq™ technology, as these factors occupied a significant portion of the cost of NGS analysis.”

For the last few decades, Sanger sequencing has been the standard for analyzing DNA sequences. Due to its need for repetitive primer design, primer synthesis and sequencing steps during Primer Walking when analyzing long sequences, however, it requires lengthy experimental time and large costs to perform.

Additionally, issues such as high repeat experiment rates, intermittent errors and a less than 1 kb read length limitation have made sequence analysis difficult for clients.

To overcome these limitations, Celemics created an NGS-based molecular barcoding technology and NGS error elimination algorithm solution, allowing for the analysis of sequences with lengths greater than 1 kb without the need of sequencing primers.


Using Celemics’ BTSeq™ - Standard Service, our clients can get accurate
results, even if the sequences are not easily readable via Sanger sequencing due to
secondary structures.

Celemics is capable of lowering the Library Preparation and analysis cost significantly by
developing our own proprietary BTSeq™ Library Preparation Reagents, as these are the
important factors determining the cost for NGS analysis.
