Gyros Introduces New Application
The application incorporates essential sample pretreatment steps, used to improve the drug tolerance of an ADA assay (the assay’s ability to detect ADAs in the presence of free drug), into an automated, nanoliter-scale assay workflow. Overall run times are reduced and technical performance improved compared to alternative techniques.
The new Gyrolab ADA assay format performed well when used with customer samples at beta-test sites, producing results that were within the current recommendations for sensitivity in the presence of high free drug concentrations.
The application comprises a new Gyrolab ADA CD, Rexxip ADA buffer and dedicated, 21 CFR Part 11 compliant, Gyrolab ADA Software that guides the user through the standard ADA analysis workflow from assay development and validation to screening and confirmatory analysis. Drug tolerance is achieved by subjecting samples to an acidic incubation step to dissociate any drug-ADA complexes. Samples are then neutralized and assay reagents added prior to measurement. Automation together with full control over assay-specific incubation times ensures consistent performance and facilitates assay validation.All products are optimized for use with the company’s Gyrolab workstation.
Erik Walldén, CEO at Gyros, explained further, “We have worked closely with key players in the biopharmaceutical industry to incorporate this proven, accepted sample pretreatment step into our automated, nanoliter-scale assay format and to ensure that the Gyrolab ADA Software module supports the entire workflow through to data evaluation.” Mr. Walldén continued, “With the launch of the Gyrolab ADA solution we have expanded the utility of the Gyros immunoassay platform that is already proven to increase workflow efficiency for applications such as pharmacokinetic and pharmacodynamic studies, biomarker monitoring and impurity testing. This unique solution offers Gyrolab workstation users an efficient alternative to existing assay formats for a critical application and supports our long term objective of setting the industry standard for immunoassays within the time-critical workflows of the biopharmaceutical industry.”
