To address the emerging needs of the research community,
the CCIB DNA Core is continuously expanding its diverse portfolio of genomics solutions.
In support of the scientific community's enthusiastic embracement of the CRISPR/Cas9 genome editing
technology, we have developed a cost-effective, high-throughput strategy for identifying
CRISPR/Cas-induced mutations via deep sequencing of PCR amplicons.
We are offering this service on a weekly basis.
Start of Next Service Cycle:
The turnaround time for our NGS service is currently 1-2 weeks. We appreciate your patience during these challenging times!
Individual samples must be received
at the core facility
no later than 4 pm on Wednesday, . If you are using one of our dropbox locations for sample delivery, please place the order in the cooler by Wednesday mid-morning to ensure timely delivery.
If you should miss the deadline or if the total customer order volume exceeds
our current production capacity, your samples will be entered into the queue and
processed in the subsequent run. Results for all samples processed in our weekly run will
be available within 7 to 8 business days after the start of the service cycle.
Full 96-well plates can be submitted on any business day and will be processed on a first come, first serve basis. The waiting time
in queue depends on the total volume of plate orders and our processing capacity. Please
contact us at least 5 business days before your sample plate
arrives at our core facility so that we can schedule your project in a timely manner and process it as quickly as possible.

- Fast turnaround time
CRISPR Amplicon Sequencing Details
- The site of interest (i.e CRISPR cut site) must be within the first
100 base pairs of the amplicon (from either the 5'-end or the 3'-end) to ensure high quality data.
Both the NGS adaptors and a unique barcode will be added as part of our NGS sample preparation process.
- Our current approach has been designed to generate complete sequence coverage for 200-280 bp
amplicons. If the identification of amplification primer binding sites should present a problem
for designing amplicons of this size, the submission of longer amplicons (up to 500 bp)
will be acceptable.
In this case, however, only the 5'-end and 3'-end of the amplicon will be covered by NGS reads, i.e. the middle of the amplicon will have a gap (represented by NNNNNNN....).
To obtain complete sequence coverage of 400-600 bp CRISPR amplicons, please submit your sample(s) for our
