Welcome to TOCS!

Dear valued customer,

As of June 1, 2017, TCAG’s DNA synthesis facility has ceased its in-house oligo production service.

TCAG Online Customer Services system (TOCS) is no longer accepting new orders. The TOCS server will be permanently shut down on September 01, 2017. If you have any data from past orders residing in TOCS, please retrieve your data before September 1, 2017. After this time, we will no longer be able to access any data on TOCS.

The IDT-TCAG web portal will remain in operation to serve your synthesis and synthetic biology reagents needs. If you do not already have an IDT-TCAG portal account, you can create one at Thank you for your support over the years.

Please contact the DNA synthesis facility if you have any questions:
