Sanger sequencing, also known as Sanger DNA sequencing or the chain-termination method, is a foundational technique for determining the exact nucleotide sequence (A, T, C, G) in DNA fragments. Developed by Frederick Sanger in 1977, it remains the gold standard for high-accuracy, short-to-medium length DNA sequencing.
The method relies on controlled termination of DNA synthesis using dideoxynucleotides (ddNTPs). As DNA polymerase builds new strands, ddNTPs randomly stop the reaction at specific bases, generating fragments of varying lengths. These fragments are separated by capillary electrophoresis and read as a clear, accurate sequence with typical read lengths up to 1,000 bases and Phred20 quality.
At Quintara Biosciences, we leverage this proven technology to deliver reliable results with overnight turnaround, competitive Sanger sequencing cost, and specialized expertise in difficult templates.
Sanger sequencing works by combining DNA polymerase, sequencing primers, standard deoxynucleotides (dNTPs), and fluorescently labeled dideoxynucleotides (ddNTPs) during DNA synthesis. As DNA strands are extended, ddNTPs terminate strand elongation at specific bases, generating DNA fragments of different lengths.
These fragments are then separated by capillary electrophoresis, allowing the DNA sequence to be accurately determined from the resulting fluorescent signal patterns. PCR amplification is commonly used before Sanger DNA sequencing to generate sufficient target DNA for analysis.
Sample tube type: please use 8-strip tubes. If the number of samples is large, a 96-well plate may be used; please clearly indicate whether the samples are arranged by row or by column.
Primer tube type: please use individual microfuge tubes. (Primers should be 18–25 bp in length, with a GC content of 40–60% and a melting temperature (Tm) of 55–60 °C, while avoiding secondary structures or primer dimers. Recommended primer concentration is 5 μM.) You can either use Quintara free universal primers.
Submit the order on the QuinGo online portal and print the sample submission form and place it in the sample bag together with the samples.
Send the samples by mail or drop them into the drop box before the cutoff time.
