In Observance of U.S. Holiday, President's Day, Agilent Cross Lab/ iLab Operations Software Support Help Desk will be closed during U.S. hours on Monday February 18th, 2019. We will resume regular U.S. support hours on Tuesday February 19th, 2019. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.

MDACC Functional Genomics Core

Overview of Services

The discovery of short hairpin RNAs (shRNAs) suppressing gene expression in mammalian cells enables large-scale loss-of-function screens by using genome-wide shRNA libraries. Genome scale over-expression libraries allow large-scale gain-of-function screens. The ShRNA and ORFeome core makes available to the MDACC research community the human and mouse shRNA libraries, human ORFeome collaboration and LentiORF libraries ( The core facility can provide individual shRNA plasmids and cDNA clones for MDACC laboratories, or carry out a screening experiment using the libraries. Purchase of clones or libraries through the shRNA and ORFeome core reduces costs and decreases turnaround time for researchers.

Available Libraries:

Human and mouse ShRNA libraries: GIPZ Lentiviral shRNAmir libraries targets the entire human and mouse genome with multiple shRNAmir per target gene.For details, please visit:

Human ORFeome Collaboration: each clone contains a sequence-verified open reading frame (ORF) subcloned into Gateway™ recombinational entry vector.For details, please visit:

Human Precision LentiORFs: an expression-ready library, lentiviral ORFs. For details, please visit:
