Check Library

This step checks the concentration and quality of the final libraries.

1. Quantify 2 μl of each sample using a Qubit High Sensitivity kit.
2. Assess average fragment size using an Agilent Bioanalyzer or Tapestation.
If necessary, dilute samples to make sure that they are within the appropriate range for the device.
Load an appropriate volume of the purified library on the fragment analyzer.

Recommended loading concentration is 1–10 ng/µl on Tapestation or 1–2 ng/µl on Bioanalyzer.
