DNA Sequencing
Sentebiolab sequencing services are available for all your sequencing needs. Using ABI Prism Genetic Analyzer, PGM Ion Torrent and Illumina MiSeq devices, we can sequence your genetic material by either conventional Sanger sequencing or Next Generation Sequencing and deliver your results electronically in a short time.
We guarantee up to 600 bp in Sanger Sequencing and we can sequence up to 20 kb of genetic material via next-generation sequencing.
Sanger Sequencing
With Sanger Sequencing, gel or column-purified PCR products and plasmids can be used as starting material. We also perform sequencing services for “Ancient DNA Samples”. Sequencing results can typically be obtained for up to 600 nucleotides. The resulting output of sequencing depends on the purity and quality of the starting material. If desired, we can design and synthesize suitable primers. With paired-end sequencing, it is possible to obtain more accurate results. In our lab, the ABI Prism 3130 Genetic Analyzer is used for sequencing services.
General information
The working principle of the machine is the generation of a monochromatic light via a laser located within the electrophoretic units. The gel-matrix that the DNA is loaded into is scanned by the monochromatic light. In the electrophoresis step, when the region with the fluorescent dye-bound DNA is arrived at, a signal is given and a characteristic wavelength of light is scattered. This signal is received by the detector and the results obtained are assessed and then turned into sequence data.

- Concentration of DNA sample (for plasmids, at least 80 ng/μL and 5-10 μL/reaction is recommended; for PCR products, at least 10 ng/μL and 5-10 μL/reaction is recommended)
- Gel image and spectrophotometric measurement results (concentration, A260/280 and A260/230 values) for PCR products (run in 2% agarose gel) or plasmid, phage, cosmid or BAC DNA (run in 1% agarose gel).
Requirements for DNA Sequence sample delivery
- Sentebiolab accepts both purified and unpurified PCR products and plasmid DNA
- To ensure optimal concentration, we recommend the values shown in the table below
- To ensure that there is only one band in purified PCR products, they should be checked by gel electrophoresis.
- Samples must be clearly labeled.
| Sample | Concentration | Volume / RXN |
|---|---|---|
| Plasmid | 200 ng/μl | 10 μl |
| PCR products | 50 ng/μl | 10 μl |
| Primer | 10 μM | 10 μl |
- All of your samples, including the primers, should be provided in 1.5 mL, 0.5 mL or 0.2 mL tubes and should be labeled in the manner in which you wish the sample to be identified.
- Sentebiolab is not responsible for problems such as leakage, evaporation or cross-well contamination (due to the samples not being prepared in the proper manner) or problems arising during delivery.

Next-Generation Sequencing
Sentebiolab utilizes the Ion Torrent Personal Genome Machine (PGM) to provide next-generation sequencing services. The PGM sequencer is a bench-top system that utilizes semiconductor technology. It enables rapid and scalable sequencing. Ion Torrent Technology uses a large number of parallel semiconductor sensors to quantitate (in real-time) hydrogen ions released during DNA replication.
Compactly organized arrays of wells serve as reactors for millions of parallel reactions. Integrated fluidics enable the flow of reagents from these wells into the array of sensors. These unique fluidics, with the help of micromachinery and semiconductor technology, translates genetic sequence into digital data and can have an output of up to 2000 Mbs (318 chips). An average sequencing process takes about 2-3 hours.
Our lab provides the following services using Ion Torrent PGM and MiSeq next-generation sequencing platforms:
- Amplicon Sequencing
- Targeted Sequencing
- Small RNA and miRNA Sequencing
- Virus Typing
- Microbial Sequencing
- De Novo Sequencing
