Capillary-based Sanger sequencing is the “gold standard” for routine sequencing in both basic life science research and clinical applications. Whether your goal is to validate a plasmid construct or discover rare genetic mutations in your clinical study cohort, Omega Bioservices offers quick and accurate sequencing of any DNA template of your choice. We use the BigDye Terminator v3.1 chemistry to perform capillary sequencing on our Applied Biosystems 3100/3130/3730xl DNA Analyzers.

|Template Type/Format||Sample Requirements||Preparation|
Minimum volume of 20 µL
|Submit DNA in DI water, preferably in capped PCR strips. Omega Bio-tek Plasmid Mini/Midi Kits are recommended for extraction due to consistent yield and purity of plasmid DNA.|
|PCR product (purified)||50 ng/µL
Minimum volume of 20 µL
|DNA should be free of contaminants, unused primers and dNTPs. Submit in DI water. Omega Bio-tek PCR clean-up kits are recommended (Cycle Pure, Gel Extraction, Mag-Bind® E-Z Pure)|
|PCR product (unpurified)||100 ng/µL
Minimum volume of 30 µL
|Additional charges apply for clean-up of unpurified PCR product|
|Difficult sequence||100 ng/µL
Minimum volume of 40 µL
|Submit sample in DI water, preferably in capped PCR strips|
|Individual tube||1.5 mL microcentrifuge tube, lypholized or in water at RT||N/A|
|96-well plate||A strip cap is recommended for sealing with samples in lypholized form or in DI water at RT.
Full-skirted or semi-skirted plates are recommended. Seal tightly to avoid evaporation or contamination during shipping.
|Prepared samples should be of equal concentration and size. See below for premixing guidelines.|
Primer Preparation: The list of primers below are provided at no extra cost:
|Primer Name||Sequence (5′ -> 3′)||Bases|
If customer wishes to supply their own primer(s), please meet the following guidelines:
- Primers should be submitted at a concentration of 5 µM in water at minimum volume of 100 µL
- High purity, free of salts, EDTA, and other contaminants
- No secondary priming sites, mismatches, or significant hair pins (>3bp)
- Should be 18-25 bp
- GC content 40-60%
- Tm (melting temperature) 55-60°C
Note: Use of customer primers in a 96-well format requires premixing.
- Template: 300 ng plasmid DNA or 50 ng PCR DNA per well
- Primer: 3.2 pmol per well (for example, add 2 µL of 1.6 µM primer)
- Add water to adjust the total volume to 5 µL
- Exon sequencing and mutation discovery: We will extract DNA from your samples (blood, tissue, cell line and more), design primers for the genes of your interest, PCR amplify the genomic regions, sequence the amplicons in both forward and reverse directions, perform multiple sequence alignment analysis, and provide a detailed mutation map.
- Plasmid library sequencing: We will perform transformation, cell growth, plasmid preparation and full sequencing analysis.
