library_construction_protocol: Muscle cells at each collection time-point, media was aspirated, and cultures were lysed on-plate using 350 µL of RLT buffer (Qiagen Cat. No. 79216) and immediately transferred to 1.5 mL tubes and stored at -80 °C. Total RNA was extracted from whole blood NHP samples collected in PAXgene Blood RNA Tubes (Qiagen, BD Diagnostics) pre- and 2 days post-immunization using the MagMAX™ for Stabilized Blood Tubes RNA Isolation Kit (Invitrogen) on an automated KingFisher Flex System (Thermo Scientific). The quality and yield of RNA were assessed on the 4200 TapeStation System (Agilent) and NanoDrop™ Eight Spectrophotometer (Thermo Scientific). Sequencing libraries were then prepared using the Illumina Stranded Total RNA Prep with Ribo-Zero Plus kit and sequenced on the NovaSeq 6000 Sequencing System (Illumina) using the S4 Reagent Kit v1.5 (200 cycles).
