The Pre-made Library Sequencing service is intended for researchers who perform NGS library preparation in-house and only require high-quality sequencing on our platforms.

1. Technical requirements for samples (libraries)

To ensure the highest data quality and optimal process efficiency, libraries must be supplied in the appropriate amount and concentration. The required library concentration and volume depend on the planned service and the total data output per library (Gb). Please provide samples according to the following specification:

LIBRARY PARAMETERS4 items
Planned data outputMinimum library concentrationMinimum volume
Gb ≤ 10≥ 1 nM≥ 25 µL
10 < Gb ≤ 50≥ 2 nM≥ 25 µL
50 < Gb ≤ 100≥ 3 nM≥ 25 µL
Gb > 100≥ 4 nM≥ 25 µL

2. Required information (Information Form)

Before a quote can be prepared and the feasibility of sequencing pre-made libraries assessed, detailed information about the library preparation procedure must be provided, including:

WHAT TO PROVIDE5 details
General informationSample/pool name, number of libraries in the pool, type of input material, species/strain and type of buffer in which the library is suspended.
Material quantityTotal amount, exact volume (µL) and concentration (nM or ng/µL).
Technical informationLibrary purification method and the name of the Library Preparation Kit used.
Demultiplexing informationIndex names and sequences (i7 and i5).
Custom PrimersInformation on whether custom sequencing primers are required (Custom Read 1, Read 2, Index 1, Index 2).
