What we do

The Gene Modulation Services Shared Resource, a partnership between Roswell Park Comprehensive Cancer Center and the State University of New York at Buffalo (UB), provides a centralized, cost‐effective service supporting investigators interested in modulating gene expression.

The resource houses individual short hairpin RNAs (shRNAs) in retro- or lentivirus vectors (140,000 for human and 84,000 for analog genes), pooled genomic shRNA lentivirus screening libraries, pooled CRISPR-inhibitor or CRISPR-activator sgRNA lentivirus libraries and associated dCas9 regulators, the human ORFeome 8.1 lentivirus library with 13.5K individual full-length cDNA clones, and various virus vectors expressing selection markers (e.g., GFP or puromycin-resistance) or immortalization genes.

Technology

Expression Arrest pGIPZ Lentiviral genome-wide Human shRNA Library and the Expression Arrest pSM2 Retroviral genome-wide Human and Mouse shRNA Libraries

These libraries, purchased from Thermo Fisher (at the time Open Biosystems), contain ~62K unique shRNAmir constructs targeting the entire genomes (>25,000 genes) with ~3-5 constructs/target.

More information on these libraries is available on Dharmacon's website and Drexel's website.

Expression Arrest pSM2 Retroviral shRNAmir Human Cancer shRNA Library

2311 shRNAmir constructs targeting 967 human cancer-related genes.

Dharmacon™ Decode™ Pooled Human Lentiviral shRNA Screening Library

Decode lentiviral RNAi screening libraries are pools of Dharmacon™ GIPZ™ shRNAs. Through RNAi-mediated silencing of hundreds or thousands of genes in parallel, a pooled lentiviral shRNA screen can be performed to identify genes that regulate cellular responses and signaling pathways, or to discover novel gene functions.

For more information on this library, please see Dharmacon's website.

DECIPHER™ Pooled shRNA Human and Mouse Lentiviral Libraries from CELLECTA

These barcoded lentiviral shRNA were made to cover the entire annotated human and mouse gene sets with a high percentage of functionally validated sequences and inclusion of a redundant set of five to six shRNA per gene. The DECIPHER libraries are broken down into modules: three modules for human and two modules for mice. Each module targets roughly 5,000 genes ̶ variously associated with diseases, known drug targets, or signaling pathways ̶ and represents over 25,000 unique shRNAs. The libraries use optimized 18-nt barcodes that facilitate the identification of functional shRNAs and high-throughput sequencing data analysis using the Illumina platform.

For more information of these libraries, please see Cellecta's website.

MGC premier Human Lentiviral ORF Library

This human Lentiviral ORF Expression Library was developed through the collaborative efforts of Dana-Farber Cancer Institute, The Broad Institute and the Center for Cancer Systems Biology (CCSB). The collection includes 15597 clones covering 12861 genes.
