What is the typical yield of a CleanPlex or CleanPlex UMI library?

CleanPlex and CleanPlex UMI workflow generates a single peak of library of approximately 8,000 – 20,000 pM when measured with a fragment analyzer such as Agilent™ 2100 Bioanalyzer instrument and Agilent™ high sensitivity DNA reagents, or approximately 1.5 – 4 ng/µl when measured by Qubit™ dsDNA HS Assay Kit, depending on each specific panel. It is good practice to QC completed library with a fragment analyzer to confirm the quality of the library prior to sequencing. Qubit measurements only give the total yield, and does not indicate if the library was poorly prepared and had resulted in large amount of byproducts.

Concentrations higher or lower than the typical range of yields may lead to lower uniformity due to uneven amplification of target regions. Concentrations much lower in concentration can have difficulty satisfying Illumina’s loading criteria. Please refer to Illumina’s suggestions for minimum loading concentration and volume.
