Sending samples the right way for our PlateSeq Service
Sending samples according to the requirements below helps us to do our job better and provides you with accurate results
Sample submission and preparation for Plasmid DNA, purified PCR products and premixed samples (mixture of DNA and primers)
- Use either our PlateSeq Kit for purified DNA or premixed samples or use the 96well FrameStar® PCR plate* from our plate accessories
- Plates with purified DNA may contain plasmids and PCR products
- Template concentration must be normalised across the plate
- One plate position should be kept free for internal quality control
- DNA samples should be sent liquid in a total volume of 15 µl
- Seal your plates using 8-cap strips to prevent material loss
- Label the plate with your order number and plate name on the plate frame if you are using your own plates
- Ship samples at ambient temperature to our sequencing lab

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

Sample submission and preparation for unpurified PCR products
- Use either our PlateSeq Kit for unpurified PCR products or the 96well FrameStar® PCR plate* of our plate accessories
- Concentration must be normalised across the plate
- PCR product size should not vary by more than a factor of 3
- One plate position should be kept free for internal quality control
- PCR products should be sent liquid in a total volume of 15 µl
- Seal your plates using 8-cap strips to prevent material loss
- Label the plate with your order number and plate name on the plate frame if you are using your own plates
- Ship samples at ambient temperature to our sequencing lab

Sample submission and preparation for plasmid clones as stab culture in soft agar
- Use either our PlateSeq Kit for plasmid clones or our agar plates with appropriate antibiotic
- Use sterile toothpicks to pick single colonies from your petri dish and inoculate a single well with one colony
- Cover the plate with a lid and loosely wrap with cellophane
- Incubate plate at 37°C for 8-12 hours (overnight)
- Label the plate with your order number and plate name on the plate frame if you are using your own plates
- Seal the plate with an adhesive plastic foil and ship your stab cultures at ambient temperature to us
Sample submission and preparation for plasmid clones as freeze glycerol cultures
- Only use transparent 96well microtiter plates with a total volume of 350 µl/well
- Fill each well with 200 µl of liquid medium (e.g. LB-medium) including the appropriate antibiotic and add 40 µl glycerol (final glycerol concentration: 10-20%)
- Ensure that liquid cultures are sent only in glycerol!
- Use sterile toothpicks to pick single colonies from your petri dish and inoculate a single well with one colony; or transfer already arrayed clones from a storage glycerol plate to a freshly prepared 96well plate using a multi-channel pipette
- Cover the plate loosely with a lid and incubate at 37°C for 8-12 hours (over night)
- Verify that the plate surface is dry before you manually seal the plate tightly with an adhesive plastic foil to prevent material loss
- Label the plate with your order number and plate name on the plate frame
- Freeze the plate at - 80°C
- Ship your glycerol cultures on sufficient dry ice to prevent sample decay

Sequencing primers
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:
- Exactly 10 pmol/µl primer concentration is required per sequencing reaction
- Each primer must have a total volume of 15 µl (double distilled water or 5mM Tris-HCl); 5 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
