Gyros announces availability of Protein A immunoassay kit for Gyrolab xP workstations


Using the same immunoassay platform, both product and impurities can be quantified during process development and production of biotherapeutics

Gyros AB, a leader in utilization of microfluidic technologies to miniaturize and automate immunoassays, announced today that Cygnus Technologies Inc. has launched a third immunoassay kit specifically designed for compatibility with the company’s Gyrolab™ xP workstation. The new kit enables scientists to test for the presence of Protein A, an impurity that can occur in any antibody-based therapeutic that has been purified using affinity chromatography. Two Host Cell Proteins (HCP) Kits are already available for detecting impurities from E.coli or CHO cells during bioprocess development and production.

Scientists optimizing purification processes and working in process control, routine QC and product release testing can now accelerate assay development timelines and maximize productivity through the convenience of three, ready-to-use kits and the automated immunoassay platform from Gyros.

Ken Hoffmann, President at Cygnus Technologies, explained: “At Cygnus we specialize in providing analytical products for testing biologics and their impurities. By continually adding to our range of kits compatible with this assay platform we will enable our customers to further increase the productivity of their labs.”

Commenting on the announcement, Erik Walldén, CEO at Gyros, added: “Biopharmaceutical companies and their service providers, CROs and CMOs, already use our platform to increase the efficiency of their workflows. For example, users of Gyrolab workstations have cut assay development times down to days compared to the weeks required for conventional techniques. Application-specific kits from independent suppliers strengthen our offering and demonstrate the acceptance of our nanoliter-scale immunoassay platform within the industry.”

Kits will be sold and supported through Cygnus Technologies.
