Keck DNA Sequencing Facility
9 AM - 5 PM
Building: 300 George St, 2nd fl, rm 2127
Keck DNA Sequencing will be closed on November 27 & 28, 2025 due to the university's holiday. Please plan your experiments accordingly.
About Keck DNA Sequencing
The Keck DNA Sequencing Facility provides competitive and timely DNA sequencing in an efficient and cost-effective manner. Sequencing is carried out on our Applied Biosystems 3730xL DNA Analyzers, along with Applied Biosystems Big Dye chemistries.
Available to Yale researchers & external researchers
Sample submission
Cutoff time for Friday processing is 3PM for Sanger sequencing, and 4PM for other services. Standard turnaround time is 1 business day*. (*CLA turnaround time is 5 business days.) Yale users will receive priority over non-Yale users. If your samples are RUSH samples, please make us aware of this before we receive your submission.

DNA/RNA QC analysis service
QC using the Agilent TapeStation 2200 allows researchers to analyze the quantity and size of DNA or RNA while using only a few microliters of precious sample.
Available to Yale researchers & external researchers -
Fragment analysis
Our 3730XL DNA Analyzer uses fluorescence-based detection to determine the size of DNA fragments.
Available to Yale researchers & external researchers -
Human cell line authentication
Using a cell line authentication service can help to establish the identity of a cell line or confirm that it remains uncontaminated. With the use of the CLA Identifiler Direct Kit, we will perform STR genotyping by fragment analysis. This STR profile will be the key to authenticating the cell line.
Available to Yale researchers & external researchers -
PCR purification
PCR purification by plate format is available to experienced users who are confident in their methodology for PCR and primer preparation. We purify and sequence your submission.
Available to Yale researchers & external researchers -
Sanger sequencing
Costs start as low as $2.22/well and $4.00/tube submission. Sequencing performed using Thermo Fisher technologies and can be submitted in tube format or 96-well plate format.
