The University of Michigan Bru-seq Lab is a core facility that provides nascent RNA sequencing services for samples prepared using the Bru-seq suite of techniques. We serve researchers from the University of Michigan, and other institutions in the United States and around the worldUsers can request services for these four assays:

  • Bru-seq: To measure synthesis of RNA
  • BruChase-seq: To measure stability of RNA
  • BruUV-seq: To identify transcription start sites and capture unstable transcripts such as enhancer RNA and PROMPTs
  • BruDRB-seq: To measure RNA Polymerse II elongation rates via RNA


 Our services

  • Total RNA and nascent Bru-RNA isolation
  • cDNA library preparation
  • Paired-end 150bp Next-Generation Sequencing (using the University of Michigan Advanced Genomics Core)
  • NGS sequencing data processing
  • Data storage 


What steps should I follow to submit a sample?  


Please refer to the Protocols section for information regarding preparation of samples for the four Bru-seq assays.

  1. Create an “Experimental Plan” request under the Request Services tab.
  2. Once you submit the form, we will process it on our end and reach out to you if we have any questions.
  3. Once the “Experimental Plan” form has been approved, please submit a  “Bru-seq Sample Submission Request” under the Request Services tab.
  4. Once the “Bru-seq Sample Submission Request” has been approved, please either edit or schedule a sample Drop-Off, under the Schedule Drop-Off tab. Please go to "View Schedule" to reserve your time. If you are mailing us your samples, you can skip this step.
  5. Once we receive your samples, they get put in a queue. We are unable to commit to a turnaround time as the processing time is usually highly variable, but will remain in contact with you through iLabs with updates. 


Sample drop-off:


Sample drop-off must be prearranged. Please refer to the "Location and hours of operation" section before scheduling a drop-off.


Please submit samples in TRIzol unless prior permission has been obtained.

Exception: Samples can be submitted as cells in culture (plates, flasks) only by UofM NCRC occupants. 


Mailing samples:


Samples must be submitted in TRIzol.


Please ship your samples on dry ice to this address:
