If you see no peaks, make sure you are analyzing sequencing libraries and NOT raw CUT&RUN yields.
Remember, Bioanalyzer/TapeStation analysis is only to be conducted on prepared sequencing libraries and NOT raw CUT&RUN DNA.
If you are analyzing sequencing libraries, read below.
Potential reasons for no peaks in fragment distribution traces for sequencing libraries include:
Low CUT&RUN yields and/or low inputs for library prep. See this article for guidance and troubleshooting tips.
Sub-optimal library prep technique. Use the EpiCypher CUTANA™ CUT&RUN Library Prep Kit (EpiCypher 14-1001 & 14-1002), specifically developed for CUT&RUN.
