Infinium Beadarray iScan Services

We are open for business! We are happy to be back. During Phase 1, we will be operating at reduced capacity. We will make every effort to keep turnaround times short as we understand there are many projects that have been waiting. We appreciate your patience and business. The UW Biotechnology Center is following University guidelines regarding COVID-19.
