DNA sequencing is the process by which the order of the bases, or nucleotides, in a strand of DNA is determined. Sanger sequencing is a method of DNA sequencing where a DNA sample is reacted with fluorescently labeled chain terminating nucleotides that are incorporated into the DNA strands at different strand lengths. Each fluorophore corresponds to one of the four DNA bases (C, T, G, or A). Once these labeled bases are incorporated, the DNA samples are analyzed using capillary gel electrophoresis (CGE). In CGE, the negatively charged DNA strands are drawn into the polymer-filled capillary via an electrokinetic phenomenon, and the strands separated based on size as they travel through the gel in the capillary. The separated DNA fragments pass a laser that excites the dye molecules. A fluorescence detector measures the fluorescence emission of the dye molecules on the strands. From this emission wavelength, the identity of the base is determined. Sanger sequencing is useful for many applications, including identification of species, confirmation or identification of mutagenesis, or verifying results using next generation sequencing techniques.
Experimental Principles

Figure 1.1: Experimental workflow for a DNA sequencing experiment. 1. Prepare samples by loading DNA samples of up to 800 base pairs onto a plate and performing chain termination PCR with fluorescently labeled nucleotides. 2. Purify samples to remove unreacted materials if necessary. 3. Load samples (10-100 Microliter/sample) into autosampler holder of the instrument. The holder can accommodate up to 96 samples in a well plate. Samples must be in groups of 4, as there are 4 capillaries that inject samples from adjacent wells simultaneously; extra wells are filled with buffer. Load the sequencing cartridge containing the capillary array and the buffer cartridge containing the cathode buffer onto the instrument. Start the run. 4. Once the run begins, samples are electrokinetically drawn into the capillaries. Negatively charged DNA fragments travel through the polymer in the capillaries and separate based on size. Longer DNA fragments carry more negative charge compared to shorter fragments. 5. Separated DNA fragments are excited by a laser and fluorescence is detected. 6. Fluorescence data is analyzed using AnalyzeDNASequencing according to calibration to the specific dye set used and the identity of the base in the sequence is determined.
Instrumentation

SeqStudio


Figure 2.1.1: Instrument schematic of Applied Biosystems SeqStudio Genetic Analyzer, an instrument used for determining the base pair sequence of DNA samples using Sanger sequencing techniques. The SeqStudio comprises a removeable cartridge housing the polymer injection system and capillary array of 4 capillaries, an autosampler, and a fluorescence detector. Once fluorescently labeled samples are loaded and the run method is set up, the instrument electrokinetically draws up samples into the capillaries, and employs capillary gel electrophoresis techniques to separate DNA fragments. The fluorescence detector measures spectral data of emissions from the fluorophores, and further analysis determines the base pairs based on calibration to the fluorophores in the dye set used to label the template. The instrument can analyze up to 96 samples in one run. DNA samples of up to 800 base pairs can be analyzed. Analysis of short DNA strands (<300 base pairs) takes 30 min for 4 samples, processing 96 samples in 12 hours. Analysis of longer strands (>600 base pairs) takes up to 2 hours for 4 samples, and 48 samples can be analyzed in a 24 hour period.

Note that if NumberOfReplicates is specified this indicates that the input samples will also be aliquoted that number of times. Note that Aliquoting (if specified) occurs after any Sample Preparation (if specified).
AliquotAmount
Default Calculation: Automatically set as the smaller between the current sample volume and the maximum volume of the destination container if a liquid, or the current Mass or Count if a solid or counted item, respectively.
Programmatic Pattern: ((RangeP[1*Microliter, 20*Liter] | RangeP[1*Milligram, 20*Kilogram] | GreaterP[0*Unit, 1*Unit] | GreaterP[0., 1.] | All) | Automatic) | Null

ConcentratedBuffer
The concentrated buffer which should be diluted by the BufferDilutionFactor in the final solution (i.e., the combination of the sample, ConcentratedBuffer, and BufferDiluent). The ConcentratedBuffer and BufferDiluent will be combined and then mixed with the sample, where the combined volume of these buffers is the difference between the AliquotAmount and the total AssayVolume.
Pattern Description: An object of type or subtype Model[Sample] or Object[Sample] or a prepared sample or Null.
BufferDilutionFactor
The dilution factor by which the concentrated buffer should be diluted in the final solution (i.e., the combination of the sample, ConcentratedBuffer, and BufferDiluent). The ConcentratedBuffer and BufferDiluent will be combined and then mixed with the sample, where the combined volume of these buffers is the difference between the AliquotAmount and the total AssayVolume.
Default Calculation: If ConcentratedBuffer is specified, automatically set to the ConcentrationFactor of that sample; otherwise, set to Null.

Programmatic Pattern: ((WellPositionP | {((Automatic | Null) | WellPositionP)..}) | Automatic) | Null
AliquotContainer
The desired type of container that should be used to prepare and house the aliquot samples, with indices indicating grouping of samples in the same plates, if desired. This option will resolve to be the length of the SamplesIn * NumberOfReplicates.
Default Calculation: Automatically set as the PreferredContainer for the AssayVolume of the sample. For plates, attempts to fill all wells of a single plate with the same model before aliquoting into the next.
Pattern Description: An object of type or subtype Model[Container] or Object[Container] or a prepared sample or Automatic or Null or {Index, Container} or list of one or more an object of type or subtype Model[Container] or Object[Container] or a prepared sample or Automatic or Null entries or list of one or more Automatic or Null or {Index, Container} entries or Null.

Basics
To perform a DNA sequencing experiment on samples that are already fluorescently labeled, simply run:

Primers may be specified to indicate that they should be added to the reaction mixtures and that chain termination PCR wil be used to prepare the samples:

PreparedPlate
If samples will undergo chain termination PCR, add master mix containing dyes, nucleotides and buffer, as well as a diluent to prepare the samples for capillary electrophoresis

Set PCR settings
If a PreparedPlate is not being used, settings for the chain termination polymerase reaction can be set

Possible Issues
Too much or too little DNA template
The amount of DNA in the sample is important, and should be quantified before preparing samples for DNA sequencing. Based on the length of the DNA sample, the concentration of the DNA samples should be changed. An amount of 20 nanograms of PCR product in a 10 microliter reaction is the minimum. More DNA should be used for longer sequences.

Dye Blobs
Indicates poor removal of the dye terminators. If BigDye products were used, purification with BigDye XTerminator is recommended to remove unreacted dyes prior to capillary electrphoresis.

Off scale peaks
If the amplicon is very efficient, or if too much DNA is in the sample, off scale peaks can occur. To fix this, adjust the InjectionTime or InjectionVoltage options, or use a lower concentration of DNA in the sample, or reduce the number of cycles in the PCR experiment to prepare the samples for ExperimentDNASequencing.
