title: Sequencing of residual DNA: Spikevax bivalent, Original/Omicron BA.4/BA.5
design: Adapter ligationbased library preparation was performed using the TruSeq DNA Nano Library Prep Kit (Illumina) without sample fragmentation and without subsequent size selection. Library preparation began with the end-repair step, followed by washing with four times the volume of magnetic beads to capture all DNA fragments present in the sample for the subsequent steps of the preparation process.
