Screensaver: an open source lab information management system (LIMS) for high throughput screening facilities.

Background: Shared-usage high throughput screening (HTS) facilities are becoming more common in academe as large-scale small molecule and genome-scale RNAi screening strategies are adopted for basic research purposes. These shared facilities require a unique informatics infrastructure that must not only provide access to and analysis of screening data, but must also manage the administrative and technical challenges associated with conducting numerous, interleaved screening efforts run by multiple independent research groups.

Results: We have developed Screensaver, a free, open source, web-based lab information management system (LIMS), to address the informatics needs of our small molecule and RNAi screening facility.

Overview of liquid handling instrumentation for high-throughput screening applications.

Liquid handling in the laboratory has unique challenges specific to the types of research being performed. The devices employed for purposes of performing liquid handling can be broken down into three general categories: bulk reagent dispensers, transfer devices, and plate washers. An overview of these types of liquid handlers, as well as common features and relevance to high-throughput applications, are discussed in this article.

An intermittent live cell imaging screen for siRNA enhancers and suppressors of a kinesin-5 inhibitor.

Kinesin-5 (also known as Eg5, KSP and Kif11) is required for assembly of a bipolar mitotic spindle. Small molecule inhibitors of Kinesin-5, developed as potential anti-cancer drugs, arrest cell in mitosis and promote apoptosis of cancer cells. We performed a genome-wide siRNA screen for enhancers and suppressors of a Kinesin-5 inhibitor in human cells to elucidate cellular responses, and thus identify factors that might predict drug sensitivity in cancers.
