“…Furthermore, whether individuals used controls or did not, they appeared to agree on the types of issues in analyzing and interpreting AIRR-seq data that would benefit from the use of controls - most importantly measuring and controlling for sample quality, assay sensitivity and specificity, and calibration for the quantification of clonal size. Also, with the progress regarding antigen-specificity inference using computational tools ( Glanville et al, 2017 ; Huang et al, 2020 ; Jokinen et al, 2021 ; Akbar et al, 2021 ; Hayashi et al, 2021 ; Richardson et al, 2021 ; Galson et al, 2015 ; Shomuradova et al, 2020 ; Chronister et al, 2021 ; Sidhom et al, 2021 ; Pogorelyy et al, 2019 ; Dash et al, 2017 ) or more conventionally through technologically challenging using antigen-binding approaches, including single-cell ( Johnson et al, 2020 ; Fuchs et al, 2019 ), having controls would be of major interest to ensure the accuracy of the TR or IG identified. It is unlikely that a single control can fulfill all of these needs across all methods and applications.…”
