Procedure:

Sequencing batch were prepared after manufacturer's protocol. (15 µl of plasmid DNA (50 - 100 ng) and 2 µl sequencing primer).

The different vectors we sequenced received the following barcodes:
- ADH in pTUM100: FR01002265

- TEF2 in pTUM100: FR01002266
- GAL in pTUM100: FR01002268

Sequencing of TEF2 in pTUM100 was not interpretable. The other sequences were consistent with the sequences in the parts registry.
