DNA tagging and Porcupine with Kathryn Doroschak (#44)

April 29, 2020

Porcupine is a molecular tagging system—a way to tag physical objects with pieces of DNA called molecular bits, or molbits for short. These DNA tags then can be rapidly sequenced on an Oxford Nanopore MinION device without any need for library preparation.

In this episode, Katie Doroschak explains how Porcupine works—how molbits are designed and prepared, and how they are directly recognized by the software without an intermediate basecalling step.
