As for the DNA samples in water or TE, bacterial cells in agar-stab, or agar plate culture, temperature control is not necessary.
Samples are stable for a few days at room temperature.

a) Single tube order :
· Agar-stab/Agar-plate culture can be shipped at room temperature.
· Glycerol stock should be enclosed with dry ice.
· We recommend to send samples/primers in 1.5ml Microcentrifuge tubes.
· Complimentary re-sequencing service is included if failed reactions are verified with reasonable reasons.
b) Plate order:
· We recommend 8 strip caps to seal the plates.
   * -U-bottom and Flat-bottom plate are not accepted.
   If you would like to use multiple primers with your plate order, the most cost-effective method is to provide “Mirror” plate of samples and primers.
· Re-sequencing is additionally charged.
   * Note :
Please prepare samples to avoid any well-to-well concentration difference or size difference for quality results.
c) Primer :
· Universal primers are provided for free of charge (ex. M13F, T7, T3)
· We have primer design and synthesis service.
- Sealing of 96 Well Plates
· Strip caps are recommended to seal 96-well plates.
· Carefully seal the 96 well plates with strip caps (8-strips or 12-strips) or polypropylene films (relatively thick and malleable).
· Aluminum sealing or polyester films are not recommended.
Place samples into strip-capped well plate as shown below.
To avoid potential damage, please use out-skirted well plate.








Seal tightly to avoid sample evaporation or contamination during transit.
Unsatisfactory results due to improper sample preparation or shipping by customer will be charged for re-sequencing.

Sample Preperation

The quality of DNA is the single most important factor in obtaining high quality sequence data.

To ensure proper concentration, please check your samples by electrophoresis prior to shipping.
There should be a single clear band of the appropriate size when loading 1 µl of the sample on a 1% agarose gel with EtBr.
Smearing or multi-bands can be causal factors in sequencing failures.
Using UV absorbance to quantify DNA may provide inaccurate measurements of target DNA concentration.

DNA should be dissolved in Nuclease-Free distilled water.
Nuclease-Free super low EDTA TE buffer (10mM Tris-HCI, pH8.0, 0.01mM EDTA) can be used but with caution.
If the TE buffer with EDTA (concentration of 0.1-1Mm) is used for dissolving DNA, EDTA take up free magnesium ions, which reduces DNA polymerase activity resulting in sequencing reaction failure.

Psomagen Sequencing Troubleshooting guide

Most of sequencing failure is caused by sample condition or the specificity of composition,
in this case there is no possibility of improvement through any other approach use, and therefore it is not the case of reanalysis Psomagen sequencing policy.
The patterns in problems have been summarized to help user's understanding in sequencing data.

Psomagen Policies for retesting

The objective of reanalysis in Psomagen sequencing service is to confirm the possibility of machine' error, operator's mishandling,
and only reanalysis is carried out in the case of that improvement is expected.

Therefore, sending a sample from a new batch is not considered the subject for reanalysis even though it is the same name.
The following failures caused by template preparation or composition should be fully paid for the analysis service.

Trouble Shooting Guide

No Signal

Pattern
· Peaks are irregular and may appear as if it is just mixed peaks. However, such peaks are actually not normal peaks but just noise signal.
· The signal strength is less than 500.
Cause
· The concentration of DNA is too low.
· The concentration of primer is too low or Tm is inappropriate for the sequencing reaction.
· The primer binding site is not on the sequence of sample DNA.
Action
  • ·To get fine sequencing result, the sample concentration is required as below;
    - Plasmid DNA (high copy number) ; 100-150 ng/ul
    - PCR product ; 25-50 ng/ul
    - When you check the sample concentration by gel electrophoresis, the band should be present on a gel
      if you load a sample on 1% agarose gel using 1ul of the sample.
  • ·Provide the primer at 5 pmole/ul or 10pmole/ul.
  • ·The annealing temperature for sequencing reaction is 50℃(fixed) so Tm is recommended around 55-60℃.
  • ·Check whether the primer binding site exists on the sequence of sample DNA.
  • ·In case of plasmid, compare the sequence between the sequencing primer and the vector to confirm whether the primer binding site exists.
  • ·Especially for primer M13R and M13R-pUC(-40), there is a difference between vector providers for primer names,
      so it is required to check the sequence all the time whether the primer´s sequence is on the sequence of the sample.
    - Primer M13R ; GCGGATAACAATTTCACACAGG
    - Primer M13R-pUC(-40) ; CAGGAAACAGCTATGAC

* The primer binding site might be damaged. We would like to recommend that you try to use an alternative primer.



No Signal

Mixed Template

Pattern
  • ·In case of plasmid, multiple peaks appear from the beginning of insertion position although clear peaks are shown up to vector position.
  • ·In case of PCR product, the following aspects appear depending on what kind of non-specific PCR product is.
    • - If the mixed non-specific PCR product has a similar size with the expected PCR product ;
      The mixed peaks are present from the beginning to the end. In case two PCR products have similar sizes, it can be shown as if it is a single band on an agarose gel.
    • -If the mixed non-specific PCR product is with Insertion or deletion;
      Sequence becomes mixed at position of Insertion or deletion although clean peaks are present in the beginning.
      For most cases, such non-specific PCR product is longer or shorter just several bases than the expected PCR product,
      this also can be shown as if it is single band on a agarose gel.
Cause
· This is because two colons were picked at the same time during Plasmid DNA preparation.
· This is because PCR products contain non-specific PCR products.
Action
· Preparing a new DNA sample is recommended.
Mixed template_2plasmids Mixed template_2PCR products Mixed template_general case

Compression

Pattern
· Multiple peaks appear from a certain point.
Cause
  • ·Compression occurs due to DNA fragments of different sizes with the same electrophoretic mobility.
    This phenomenon is thought to be caused by regions of secondary structure within the template DNA
    and as different peaks are detected simultaneously it appears as multi-peaks and although it rarely happens,
    but it can be found in the regions with a high G/C or high A/T content.
Action
· Confirm whether the result is improved by using the opposite direction primer.
Compression

Multiple Binding

Pattern
· Multiple peaks appear at a different position with good signal strength.
Cause
  • ·If accidentally more than 2 regions have homology for the primer binding sequence the primer has multiple bindings although the template is one.
  • ·When more than 2 different templates are mixed this phenomenon appears.
    When 2 PCR products with similar sizes are mixed, it looks like a single band on the agarose gel..
Action
· Design a long primer or design a new primer being able to avoid multiple binding.
· The use of an opposite direction primer can be helpful.
· If more than 2 similar sized products are mixed, redo PCR in a more optimized PCR.
Multiple Binding

Slippage

Pattern
· The phenomenon that mixed peaks appear in the back position of a long homopolymer region.
Cause
· Pairing occurs incorrectly in homopolymer region during polymerization.
Action
· Try sequencing in both directions. For example, if a slippage pattern appears when the reverse primer is used, try sequencing toward the forward direction.
· Perform sequencing by designing a new primer avoiding homopolymer region.
Slippage

Mixed base

Pattern
· Partly 1 base peak appears as a double peak in the normal sequencing data.
Cause
· It can be caused by SNP or rarely point mutation.
Action
· Compare the reaction results after several runnings if base calling is suspected.
Mixed base

N-1 Primer

Pattern
· Small peaks appear on the whole as like background.
· Lower peaks from the base which is the same as the major peaks are shown right before major peaks.
Cause
· Primer purification was not done properly during synthesis processes.
· The primer was degraded.
· The primer binding site in the sample is not appropriate.
Action
· Mostly, this phenomenon is caused by primer purification or degradation. The clear results can be obtained by sequencing with the primer resynthesized.
· Degradation can be confirmed by Psomagen MALDI (Matrix-assisted laser desorption/ionization) and Psomagen offers the service.
   (When employing oligonucleotides prepared 6 months or around 1 year ago check whether the degradation occurs
   before use or use oligonucleotides newly synthesized.
N-1 Primer(Before the improvement) N-1 Primer(After the improvement)

Frameshift Mutation

Pattern
· Minor peaks, the same as N-1 primer pattern appears from a certain point
· The difference from N-1 primer is whereas N-1 peak appears from right after primer binding in case of N-1 primer it appears
   from the middle point in case of Frameshift Mutation.
Cause
· Several products are made in a sample because one or more than one base is inserted or deleted in a template.
Action
· Sample DNA should be newly prepared.
Frameshift Mutation

Repeat Sequencing

Pattern
· It is the phenomenon that the peaks in back portion are overlapped due to the repetitive sequence (the repetition of 2 or more bases is shown).
Cause
· It is thought that polymerase processing is interfered by repetitive sequence or the secondary structure is formed.
Action
· Use the Difficult sequencing service of Psomagen.
   Difficult sequencing service of Psomagen is specialized for the case of signal decrease or sudden signal loss caused by unusual secondary structure or high GC sequence.
Repeat Sequencing

Abrupt Signal loss

Pattern
· Peaks are suddenly stopped or rapidly lower. Whereafter data are not gained.
Cause
There is secondary structure existed in the sample.
Action
· Perform sequencing toward the opposite direction of the corresponding result.
· Use the Difficult sequencing service of Psomagen. Difficult sequencing service of Psomagen is specialized for signal decrease or sudden signal loss caused
    by unusual secondary structure or high GC sequence.
Abrupt signal loss(Before the improvement) Abrupt signal loss(After the improvement)

Dye Blob

Pattern
· One or more peaks appear as wider and over-intensified peaks, commonly between 50 and 140.
Cause
· This phenomenon can be shown when the sample volume is not used properly, based on the sample concentration.
· Very small quantity of BigDye left in the clean up process appears as large dye blob peaks.
· A small amount of Big Dye remains in the Clean-up process and appears as a large dye blob peaks.
Action
· Reduce the error as measuring the sample concentration by a gel electrophoresis and spectrophotometer.
