Sequencing technology
EMBL-EBI / European Nucleotide Archive
Cumulative public ENA runs on the retired Roche/454 pyrosequencing platform. The curve is now nearly flat — 454 sequencing was discontinued by ~2016, so this is a legacy archive that barely grows. Shown in the platform-mix comparison card; counted live from the ENA Portal API.
