NGS Library Preparation | Genomics Core | School of Medicine

The Genomics Core offers a full suite of Illumina Next Generation Sequencing library prep services for both DNA and RNA projects for the Illumina platforms. We also accept pre-made libraries for sequencing. Use the tabs to view more details about the library prep services offered at the CWRU Genomics Core.

If the library prep that is of interest to you is not found here, please email CWRUgenomics@case.edu to discuss your project.

Sample Submission Requirements

1.	2.	3.
For specifics on total amount and volume required, please see RNA and DNA library preparation options in the charts below	Submit all samples in 1.5ml eppendorf tubes, clearly labeled ON TOP of tube with sample name and user name/initials. Label the SIDE of tube with the date. Sample name on tube and iLab request form should match.	Large volume projects may be submitted in FULL SKIRT 96-well plates, with at least one SIDE WALL clearly labeled with project name, plate number, user name, and date. Sample names and well location will be submitted through iLab.

10X Library Preparation

Through a collaboration with The Applied Functional Genomics Core Facility, directed by Dr. Mark Cameron, CWRU and affiliates have access to the 10X Genomics single-cell technology. The 10X Genomics Chromium System is available for multiple single cell product lines: Single Cell Gene Expression, High Definition Immunology, Single Cell CNV, and Single Cell ATAC-seq. For more information on setting up your single cell project, contact Dr. Mark Cameron (mjc230@case.edu).

DNA Library Preparation Options

All DNA submitted to the Core for processing will undergo quality control (QC) to make sure it is of high enough quality and quantity to move forward with library preparation. The QC of each sample includes Qubit for concentration (ng/ul) and agarose gel electrophoresis to check quality. The cost of the QC is included in the price of library prep. If a sample fails QC, the user will be charged for QC portion only. The Core will provide expert advice as to whether or not a DNA sample should be used for downstream analysis, but the final decision will be made by the user. Please see the NGS Run Guarantees Section for additional information.
