The clones are available as glycerol stocks, plates, DNA minipreps or midipreps (
If you need viral particles produced from the DNA preps, we can forward the DNA directly to the
Clones are distributed to Biocenter-Finland affiliated groups only.
Our collection comprises 81 534 human shRNAs and 77 994 mouse shRNAs. There are usually five different constructs that target the same gene. The constructs are in pLKO.1 lentiviral vector with puromycin selection. Carbenicillin selection is used for the growth and maintenance of the vector in bacterial cells. See the vector map and sequence
More detailed information on the constructs can be found at the
If our library does not cover your gene of interest, we can clone a custom shRNA into pLKO.1 vector or into inducible Tet-pLKO-puro vector. See

The delivery time is approximately one week.
We always recommend to sequence the clones before the experiments. The libraries are vendor-verified but unfortunately do contain some errors. You can find the sequencing primers suitable for your clone in the info sheet we send with your order. We offer a service to verify the clones by Sanger sequencing (approximately two days) or restriction analysis (one day). Please indicate in the form if you would like to purchase also the verification service and which method.
Please indicate in the form if you would like to submit the DNA directly to the
DNA preps are delivered by mail. Glycerol stocks are shipped with UPS or FedEx on dry ice on the customer's expense (customer's account number required for FedEx). For plates the delivery options are pick-up and UH internal mail.
