Can we do NGS library preparation using UMI with large amount of DNA input?

We know that in next-generation sequencing (NGS), the unique molecular identifier (UMI) can reduce or eliminate sequencing or PCR errors and result in very high accurate data. Therefore, UMI is widely ...

Are sequencing reads written differently when inserts and indexes are sequenced seperately?

I was going over different sequencing library protocols and noticed that the adapter sequence can vary between protocols. In some adapter sequences the index sits between the primer binding site and ...

Why do NEBNext indexing primers have sequence between the p5 oligo and index?

In a previous post I asked Why do NEB adapters have non-complementary sequence? Since then, I realized that there is some other sequence in the p5 indexing primer, as well as in the p7 indexing ...
