Use the following concentration and volume for your samples:

* Primer must have a total volume of 20 µl (double distilled water or 5mM Tris-HCl); 2 µl of primer volume is required for every additional sequencing reaction.

Quantify the template concentration via agarose gel or a photometer to ensure accurate results.

Premixed samples (a mixture of template and primer):

• Templates should consist of 15 µl purified DNA with either of the concentrations given in the table above
• Add 2 µl of primer with a concentration of 10 pmol/µl (10 µM)
• Ensure that the total volume of your premixed sample is 17 µl

 Please send your sample tubes according to the requirements below:

• Use 1.5 ml safe-lock tubes for your templates and primers
• Do not tape or wrap tubes with parafilm. Safe-lock tubes offer perfect sealing and evaporation protection
• Label your sample tube with one of your barcode labels. Affix the label horizontally
• Label your enclosed primers with our free Primer Barcodes

In case the DNA region of interest is CC / GT / AT rich or your samples are bisulfit samples, please select Special Chemistry on the order wizard.

If your DNA has repeats, secondary structures or are low copy plasmid like constructs >30kbp, please select Extended Cycle Sequencing.

If your DNA contains difficult-to-read stretches like shRNA constructs, please select both options.

We will perform special cycling conditions or using special chemistry. Both services require a longer processing time and are at additional charges.

Thanks to our DNA synthesis lab, bioinformatic know how and internal IT solutions you can choose how to provide us with your sequencing primers:

• Select from standard primers on stock
  Select and manage your favourite standard primers from more than 80 different validated standard primers
• Order specific sequencing primers
  Specific primers can be ordered directly with your sequencing order. These primers are stored for 4 weeks ( One year on request) and can be re-used during this time
• Enclose your own sequencing primers
  You can send us your sequencing primers in 1.5ml tubes along with your samples by using our free Primer Barcodes. Enclosed primers are stored for 10 days. 
• Premix primer with DNA template
  Sequencing primers can be added directly to your DNA template and sent to us as premixed sample.

Please consider optimal primer conditions, concentration and volume as described below.

Optimum primer conditions:

• Primers must not contain phosphorylation or fluorescent dyes
• The optimum primer length is between 16-25 bases
• The primer melting temperature (Tm) should be 50 - 62°C
• The GC content of the primer should be 35-60%
• Ideally one G or C should be located at the 3' primer end
• The number of 3' Gs or Cs should not exceed 2 Gs or Cs
• If possible, avoid >3 identical bases in a row in the sequence

Primer concentration and volume for enclosed primers:

• Exactly 10 pmol/µl primer concentration is required per sequencing reaction
• Each primer must have a total volume of 20 µl (double distilled water or 5mM Tris-HCl); 2 µl of primer volume is required for every additional sequencing reaction
• Concentration of primers with wobble bases must be calculated according to the following formula: nX x ConcPrimer

n = number of bases within a wobble according to IUPC code, X = number of wobbles within the primer sequence. [e.g. 1 V (AGC) = 3¹ x 10 pmol/µl; 2 Y (CT) (CT) = 2² x 10 pmol/µl; 1 N (AGCT) = 4¹ x 10 pmol/µl ]

 
DNA and primer storage:

• Storage of template DNA for 4 weeks
• Storage of synthesised primers for 4 weeks free of charge
• Storage of synthesised primers for one year at additional cost
• Storage of enclosed primers for 10 days free of charge
• Storage of enclosed primers for 6 months at additional cost

Data storage:

• Secure online archive of all selected sequence data for 6 months
  

Definition of technical failure

A technical failure is defined as a chemical or technical (IT, machines) defect in our lab. In order to ensure that the sequencing quality is not affected by a technical failure, an internal quality control is performed with each sequencing run. In addition to that, a sophisticated software is analysing each plate considering parameters like quality values (QV) and reading lengths.

If you see "DONE_QV_NOT_MET" as a result of your sequencing reaction, it means that the internal quality control has passed, but some sample quality values have not been met. (e.g. sample or primer concentration or volume, sequence design or structure etc.).

Important information:

Specified delivery times are mainly depending on sample arrival time in the lab.

For many European cities we are providing coordinated pick-up and transport services using Eurofins DropBoxes ensuring on time delivery in the lab.

However, these logistics services may also be subject to force majeure or unpredictable changes caused by e.g. strikes, accidents, storms, floods. In such events, Eurofins Genomics cannot guarantee the stated data delivery time and is not responsible for delays caused by logistics services.

Additionally, our general terms and conditions (GTCs) apply.
