NEB recommends utilizing a minimum of 6 ONT Native Barcodes per sequencing run. For runs utilizing 6 to 12 barcodes, we recommend inputs of 350 ng of amplicons within the 400-1,400 bp size range per sample going into the end prep reaction for ONT library prep.
If utilizing more than 48 barcodes, 20 ng – 40 ng of amplicons within the 400-1,400 bp size range per sample can be used as input for the end prep reaction for ONT library prep.
