Biomedicum Functional Genomics Unit Libraries

FuGU/Libraries maintains and distributes human and mouse genome-wide, arrayed lentiviral vector -based shRNA (The RNAi Consortium (TRC) library, Broad Institute) and CRISPR/Cas9 gRNA (Sigma-Aldrich) libraries. The shRNA libraries consist of 160,000 distinct constructs, whereas the gRNA libraries contain altogether ~ 80,000 clones. Non-targeting control constructs for both gRNA and shRNA constructs are also available. Main services include the production of glycerol stocks, DNA preparations, standard and concentrated recombinant viral particles from the libraries and customer-provided constructs. Additionally, shRNA/ CRISPR library knockdown/-out validation is done as a service by using LightCycler 480 instrumentation and Universal ProbeLibrary (UPL) probes (Roche). FuGU/Libraries is a non-profit core facility. Reagent, equipment and labor expenses are charged from UH customers, whereas for external customers overheads are charged. Pricing has been done according to the University of Helsinki finances instructions.
