How tos and FAQs

How do I order Sanger sequencing or Fragment analysis?

All orders are placed through our web interface. To order analyzes, you must... Read more

General rules of sample preparation

When ordering sequencing or fragment analysis in tubes, preferably please use 0.2 ml strips to send samples, they are easy to work with. Read more

How do I ship samples?

We recommend you insert samples into a quick-closing plastic bag. Fragment analysis samples can be (not necessarily) wrapped up in aluminium foil to prevent light access. Read more

StandardSeq – Preparation of samples

Sample is a template mixed together with sequencing primer in a single test tube / well or template only if you wish to use some of our universal primers. Template is a PCR product or plasmid. Read more

RapidSeq - Preparation of samples

Please use the instructions for the StandardSeq protocol. Read more

ColonySeq – Preparation of samples

Sample is bacterial cells from agar plate colony, liquid media culture, or glycerol stock. This protocol is designed for mid- to high-copy number plasmids (> 10 copies per cell). Read more

CleanSeq – Preparation of samples

Sample is an unpurified PCR product (aliquot of the PCR reaction) or other suitable template, amenable to enzymatic cleanup. You must also supply sequencing primer(s) or select some of our universal primers. Read more

HairpinSeq – Preparation of samples

Sample is typically a plasmid with a cloned hairpin or GC-rich stretch in the region of interest or PCR product. Price of the HairpinSeq protocol includes bidirectional sequencing (forward and reverse). Read more

What is the difference between sequencing protocols you offer?

StandardSeq is the basic protocol, we sequence your template. CleanSeq is in fact StandardSeq with template cleanup performed beforehand. HairpinSeq is a special protocol ... Read more

Fragment analysis – Preparation of samples

The sample is typically a PCR product or a mixture of PCR products which are fluorescently labelled. The PCR products do not have to be purified, you only need to send the aliquot of the PCR reaction. Read more

Can I copy-paste into the order form?

Definitely yes. Create (in Excel, for example) a table with three columns - Sample Name, Primer Sequence and Template Size (applies to StandardSeq, CleanSeq, ReadySeq). For HairpinSeq the table must have four columns - Sample Name, Primer1 Sequence, Primer2 Sequence and Template Size. Read more

Universal primers

The following universal primers are supplied by us free of charge. Read more

My own primers

When designing custom primers, please remember that properly designed primer is crucial for sequencing... Read more

How should I specify primer sequences?

Please use ACGTN symbols for the primer sequences, IUPAC codes (BDHRYKMSWV) for degenerate bases and “I” for Inosine. If there are... Read more

I want to use my own primer which you use as a universal primer, how can I do this?

If you want to use for example your own M13F primer, you have two choices. Either you do not enter primer information in the order form and only add it to your template (StandardSeq protocol), or you specify this primer in My Primers... Read more

How should I specify the template size?

If the template is a PCR product, enter its size. If the template is plasmid with a cloned insert, enter the total size of the template (plasmid plus insert). This field is optional for ReadySeq. Read more

There is a limit on template length in the order form for Sanger sequencing. Why?

This is correct, the template size must be between 100 bp and 20.000 bp. It is quite unusual to sequence templates shorter than 100 bp. Assuming your primer has 20 bases ... Read more

Which fields in order forms are compulsory?

Read more

Must I print and send the order confirmation together with samples?

Yes, the first sheet is just enough. Read more

I cannot send the online order

If, after entering data into the order form and clicking on the Order button, you get the notification that no sample data has been entered Read more

Where and how long do you store my results?

All Sanger/Fragment analysis orders are processed on our website. Results will be made accessible in your user profile and can be downloaded from within. Read more
