Overview

A Tag is a short, know sequence of DNA which gets applied to a sample. The tag remains attached through subsequent processing, and means that it is possible to identify the origin of a sample if multiple samples are subsequently pooled together. Tags are sometimes referred to as barcodes by our users. Tag is stored on aliquot, and an individual aliquot can have two tags identified as tag and tag2, these may also be known as i7 and i5 respectively.
