• An additional peak within the library smear appears in the analysis file.
• This peak is due to a concentration-dependent stacking effect and
represents no contamination in the library.
• This peak fronting can occur in Low Input libraries with medium to low
concentrations.
• Sizing and quantification results obtained in the Region View is still
within the given specifications.
• For examples with expected results within an Agilent SureSelect or
HaloPlex workflow please see the demo files available in the TapeStation
Analysis software.
