We will need exactly what you want to write on the barcodes: sequence number and/or library name
We suggest that you protect the barcodes with label protectors in order to extend their life
For new customers, please send us a sample of your current barcodes. We can usually have all the necessary information with a sample that shows at least 5 barcodes. A scanned and emailed sample is preferable but a faxed sample is also fine as long as it is as clear and as large as possible.
