New
automatic DNA sequencing and gene characterisation (reading of fragments)
service.
Test
equipment
In order to keep constantly abreast of the times, the Istituto Nazionale
di Apicoltura has equipped its laboratories with instruments used in
molecular biology.
The main instrument of analysis is a modern automatic sequencer (CEQ8000
Beckman Coulter), which enables us to analyse DNA sequences and DNA
fragments (microsatellites, SNPs, AFLPs).

Sequences
Reading only
After the sequencing reaction, ethanol precipitate the reaction or purify
with the special kits recommended by the manufacturer (Beckman Coulter).
Fill in the sequence –
read only order form and send it together with the test
tubes, which should be sealed with parafilm and wrapped with foil (the
pellet is photosensitive!!). If the samples are to be dispatched already
resuspended in SLS, pack the test tubes on wet ice and make sure the
samples are sent as promptly as possible (within 48 hours).
Sequencing
reaction and reading
Purify the PCR product by enzymatic reaction (Exo-SAP) or using one
of the commercially available kits designed for this purpose; quantify
the concentration of the PCR product by agarose gel electrophoresis
and/or spectrophotometry. Send a sufficient quantity for at least two
reactions (2X). The quantity of template to be sent will depend on the
type of DNA (plasmid dsDNA, M13 ssDNA, PCR products...): as a rule,
for dsDNA and purified PCR products you should refer to the
table under the heading “ng per 100 fmol”;
for ssDNA refer to the table under the heading “ng per 50 fmol”.
Send the primers at a concentration of 1.6µM, in adequate quantity
(2.0µl is required for each reaction). Fill in the
sequence – reaction + reading order form and send
it together with the test tubes, which should be sealed with parafilm
and placed on wet ice, within a few days.
Fragments
(reading only)
Send at least 10 µl of PCR product (microsatellites, SNPs, AFLP)
marked with the dye-primer. If you wish to have more than 4 fragments
run simultaneously, purify the PCR product using one of the commercially
available kits designed for this purpose or an ethanol/sodium acetate
precipitation. Fill in the fragments
order form and send it together with the test tubes, which
should be sealed with parafilm, wrapped with foil and placed on wet
ice, within a few days.
If you wish the laboratory to perform the amplification reaction as
well, please contact the technician before sending the samples.
