Nanoliter Dispensing of Compounds into Assay Plates Using Disposable PocketTipsTM Successful assay miniaturization for screening requires low volume transfer of test compounds dissolved in DMSO. Due to the low DMSO tolerance of most assays, many laboratories are required to make intermediate solutions in aqueous buffer. This may result in compound precipitation prior to compound dispensing into the assay plate. To circumvent this problem, we evaluated 100nL compound transfer using the Biomek FX 96 and 384-head compatible PocketTips. Reproducibility, precision and accuracy will be presented using fluorescent dyes and a panel of test compounds. Results from 2 enzymatic assays will be shown and the issue of ‘sticky’ hydrophobic compounds will be discussed. MP96 Marc Pfeifer Roche Molecular Systems, Inc. Pleasanton, California marc.pfeifer@roche.com Co-Author(s) Josh Weinberger Dan Bristol Mike Takeuchi Paulette Thomas Imre Trefil Jon Nunes The Cobas s 201 System: Modular Automation for NAT Blood Screening of HCV, HBV, HIV, and West Nile Virus The Roche cobas s 201 System running the cobas TaqScreen Multiplex (MPX) Test and the cobas TaqScreen West Nile Virus (WNV) Test is an automated NAT system for screening donated blood. The system is capable of handling pooled plasma specimen testing, as well as single unit resolution testing. Utilizing real-time PCR technology for nucleic acid amplification and detection can effectively help identify donations in the pre-seroconversion “window period”. The basic configuration of the modular cobas s 201 consists of a Hamilton Microlab Star instrument for pool pipetting, a COBAS AmpliPrep instrument for automated sample preparation, and a COBAS TaqMan instrument for PCR amplification and detection. A central host interface computer system running Pooling and Data Management (PDM) software is used for automated results compilation and reporting. Pooling, data management, and PCR result handling are integrated. The entire testing process for a donor is tracked in the database. Non-reactive test results are transferred to the associated donors automatically for reporting. Results requiring resolution, i.e. invalid results or valid Reactive results of a pool, automatically trigger a new pooling action to be performed by an operator. Final results are exported to a host LIS system. The full lifecycle of a donor from initial pool until final PCR result is tracked. 150
