The number of newly published repertoire sequencing papers appearing in PubMed each year over the last 15 years. For 2002, the number was obtained by the query ((repertoire sequencing) AND (2002 [dp])). The number for 2017 is a projection based on the number appearing between January and December 2017. The red arrow indicates the year in which publications demonstrated the feasibility of applying high-throughput sequencing to immune repertoires.
