The Gyrolab (TM) immunoassay system: a platform for automated bioanalysis and rapid sample turnaround

Background: The Gyrolab (TM) workstation benefits from fully, automated transfer of reagents and samples originating from a storage microplate onto a compact disc containing solid-phase microstructures composed of a 15 nl streptavidin-derivitized bead bed. Results: This paper describes the development, full validation and use of the method in a regulated environment to measure a humanized bispecific monoclonal antibody domain antibody (GSK-A) molecule using the Gyro lab immunoassay system in cynomolgus nonhuman primate plasma ranging from 5 to 250 mu g/ml. The method was subsequently used in support of the TK portion of a regulated preclinical study in monkeys. Conclusion: The Gyro lab immunoassay system proved to be a viable alternative to traditional immunoassays and was used to support a regulated preclinical TK study. The speed of analysis that the Gyro lab provides was beneficial in meeting timelines to complete this project as multiple assays and repeat sample analysis could be completed in the same day.
