Yes, Tapestri libraries are fully compatible with non-Tapestri libraries as long as the indices are unique and allow all libraries to be uniquely identified. Tapestri libraries are dual indexed with 8 bp indexes.
Note: If the non-Tapestri and Tapestri libraries have different sizes, take extra care when quantifying and pooling the libraries. Do not sequence fragments <150 bp with Tapestri libraries. Contact support@missionbio.com for additional advice.
