#44 DNA tagging and Porcupine with Kathryn Doroschak

Listen Later

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.
