RNAi Libraries
The Silence Select Human Kinase siRNA Library V4 (catalog no. 4397918) from ThermoFisher Scientific contains 2127 unique siRNA (0.25 nmol) targeting each of 709 human kinase genes.

Open Reading Frames
The HTSRC has a collection of 17,000 DNA plasmids representing individual proteins in the human genome. The plasmids are in carried in E. coli glycerol stocks, and can be used for protein expression using Gateway vector systems along with Lentiviral packaging constructs. Two versions are available. The Precision ORF collection is contained in a pLOC vector which carries blasticidin resistance and a GFP IRES-driven marker for positive clone selection.  The second version is the CCSB Broad Lenti ORF library, of 16100 clones in a pLX304 vector containing blasticidin resistance, GFP marker and a stop codon after a v5 epitope tag.

Initiating a Project
If you are interested in setting up an HTS/drug discovery project or utilizing our spectroscopic instruments please contact Assay development and screening typically require a significant financial and time commitment and advance discussions are needed to prepare for the project. This resource center is a shared facility supported by Weill-Cornell Medical College and Rockefeller University, and we welcome clients from those institutions. Due to a high demand for our services, we can accept projects from outside institutions only on a case-by-case basis.  The HTSRC does not currently support research in conjunction with for-profit entities.
