This protocol describes how to send DNA barcodes for Sanger sequencing after following the DNA Barcoding PCR Protocol using a DNA Barcoding Primer Mix.
In this step you will transfer your sample to the sequencing reaction tube and send it off for sequencing.
Prior to starting this protocol, remove your PCR amplicon (the green liquid in the PCR tube from the DNA Barcoding PCR Protocol) from the freezer and allow to defrost thoroughly.
Leave your PCR amplicon to defrost in the fridge, either for a couple of hours or overnight.
When you order a Sanger Sequencing Reaction you will receive:
For each sample, transfer the remaining PCR amplicon into a sequencing reaction tube. If you have multiple PCR amplicons, make sure to use a fresh pipette tip for each transfer.
Record on the sample list next to the white barcode number which sample you transferred to the sequencing reaction tube, and keep for your records.
Place the order receipt (2) inside the prepaid envelope (1). Make sure the lids are closed properly on your sample sequencing tube (4) before also placing these inside the prepaid envelope. Seal the envelope. Keep the sample list (3) for your own records.
Ignore (5) – this is only relevant if you used a custom primer set for the DNA Barcoding PCR Protocol.
If you cannot post straight away, place the envelope in the fridge or freezer until you can.
DNA is stable at room temperature for a few days, but it is best to coordinate postage so your samples spend as little time travelling as possible. Whenever possible, post your envelope just before the post is to be collected to avoid your samples sitting in the postbox during the day or overnight.
You should receive your sequencing results within 72 hours of posting your samples. Keep your eyes peeled for an email from Bento Lab and follow the Identifying Samples from Sequencing Data protocol when it arrives.
