Nucleic Acid Isolation

Nucleic Acid Isolation Pricing

The Molecular Diagnostics Section of the BMP Core offers nucleic acid isolation from a variety of different specimen types including blood, fresh/frozen tissue, and FFPE (including micro-dissection).  Included in the price of each extraction is nucleic acid quantification by NanoDrop and generation of a nucleic acid isolation report.  Additional fees apply for Biorepository and Research Histology Services andquantification by Qubit and Agilent TapeStation RIN analysis.

Human Specimens from the Biorepository under the General BioBanking and use IRB Protocol  

If requesting human specimens from the Biorepository through the general biobanking and use IRB protocol, please make a request to BMP-Biorepository@hci.utah.edu.  The Biorepository staff will coordinate consent validation, specimen collection or retrieval, histology, and neoplastic cell content review by a pathologist and will deliver the specimens to Molecular Diagnostics for extraction.  A GNomEx request for the nucleic acid isolation will be made on behalf of the investigator and the sample will be de-identified and assigned a CC# through itBioPath.  Upon completion, the investigator will be notified and the nucleic acid isolation report will be available through GNomEx.

De-identified (exempt) Human and Animal Specimen

Please submit a GNomEx request directly to the Molecular Diagnostics Laboratory for de-identified (exempt) human and animal specimens.  Please see the sample submission page for additional instructions.

FFPE Micro-Dissection 

microdissection 1
microdisseciton 2

 

The Molecular Diagnostics Laboratory strongly recommends Micro-Dissection of FFPE specimens to enrich for tumor cells. Many FFPE specimens contain only small amounts of tumor, which can significantly impact downstream results. We highly recommend you collaborate with a Pathologist to circle the tumor area on the H&E. The Pathology Services Page contains information about finding a Pathologist.

Turnaround Time and Low Volume Requests

Isolations will be performed in the order they were received.  The typical turnaround time is approximately 2 weeks once the Molecular Diagnostics laboratory has physically received the specimens, but may be as long as 4-6 weeks.  If a request is submitted for <4 specimens, we will wait up to one month for additional samples to be requested.  Alternatively, the investigator can pay for 4 samples and the extraction will be processed in the order it was received.
