In addition to concentration and total amount, a suitable peak pattern is also required.
Note: Lane sequencing of low diversity libraries requires PhiX spike-in to ensure robust base calling.
We recommend submitting pre-pooled libraries as samples. If you require BMKGENE to perform library pooling, please refer to the
library requirements for partial lane sequencing.
Main peak should be within 300-450 bp.
Libraries should have a single main peak, no adapter contamination and no primer dimers.
A report on the quality of the library is provided before sequencing, assessing library amount, and fragmentation.
