shRNA and ORFeome Core

shRNA and ORFeome Core

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.

The shRNA and ORFeome Core offers a few cutting-edge tools tailored for high-throughput screens. To schedule the equipment usage, please contact the core facility directly at,  Dr. Yutong Sun at, or Dr Longfei Huo at

An automated workstation EVO100 (Tecan) is located in a laminar flow hood, which can facilitate high throughput tissue culture.





An automated workstation EVO200 (Tecan) is equipped with both span8 and MCA96 liquid handling arms, a vacuum and an orbital shaker, which allows automated liquid handling, plasmid purification and manipulation in a high throughput manner.




Biotek synergy H4 plate reader is capable of performing absorbance, fluorescence and luminescence assays.






High-Content Imaging Systems:

ImageXpressMicro (Molecular Devices) is a widefield high content microscope capable of providing automated cellular imaging in fluorescent, transmitted light, and phase-contrast modes for fixed- or live-cell assays. It is also equipped with Environmental Control that allows for time-lapse imaging of live cells.



ImageXpressUltra is an automated point-scanning confocal microscope.
Both ImageXpressMicro and ImageXpressUltra  are able to perform automated acquisition and analysis of imagines in multi-well plates (up to 384-well plates).



The high content imaging systems enable investigators to perform image-based high throughput screens, measuring critical events including apoptosis, cell cycle, micronuclei, neurite outgrowth, angiogenesis, intracellular translocation, endocytosis, cell signaling, and multi-wavelength cell scoring.
