CyBio and Euroscreen Comarket GPCR High-Throughput Functional Screening Assays and Automation; CyBio's Flash Luminescence Reader CyBi(tm) Lumax SD and Euroscreen AequoScreen(tm) System Provide Ideal Combination for HTFS of GPCR


JENA, Germany, and BRUSSELS, Belgium, May 5, 2003 (PRIMEZONE) -- CyBio AG (Other OTC:CYBOF) and Euroscreen SA today announced that they have begun to offer biopharmaceutical customers a combination package which provides Euroscreen's functional aequorin-based G protein-coupled receptor (GPCR) testing with the reader technology and automation benefits of the CyBi(tm)-Lumax SD and further flexible solutions for screening automation.

CyBi(tm)-Lumax SD is already known as one of the most sensitive and robust flash-luminescence readers capable of dispensing and measuring light from 96, 384 and 1536-well plates. Due to the integration of the proven non-contact dispenser CyBi(tm)-Drop into a CCD camera-based imager, the CyBi(tm)-Lumax SD can detect short lasting flash signals. The versatility of the CyBi(tm)-Lumax SD reader with its small footprint and with its ease of integration in large automated platforms makes it the ideal workhorse for High-Throughput Functional Screening (HTFS) of GPCRs. AequoScreen(tm) is Euroscreen's proprietary platform combining the sensitivity of aequorin detection of increases in intracellular calcium with optimized GPCR expression and coupling to calcium in mammalian cell lines. Euroscreen AequoScreen(tm) cell lines are already recognized for their potential in providing a single platform for high-throughput detection of the functional activity of GPCRs in a homogeneous, automation-friendly format using the system's stability. Customers can now further benefit from these procedures through improved custom support and special pricing of the combined product package of the two companies for GPCR testing.

Commenting on the announcement, Dr. Paolo Meoni, Scientific Support Manager for Euroscreen, said: "This is what the GPCR screening community has been waiting for years. The use of AequoScreen(tm) cell lines for HTFS of GPCRs has been hindered by the lack of affordable, sensitive, robust and flexible flash-luminescence readers. The combination of CyBiTM-Lumax SD and Euroscreen AequoScreen(tm) cells lines will give an immediate opportunity to small and medium-sized biopharmaceutical companies and Big Pharma to experience the benefits of HTFS in GPCR drug discovery."

Euroscreen's AequoScreen cell lines provide specific GPCR test results based upon the luminescent signaling of aequorin which is covered by a series of worldwide patents exclusively held by Euroscreen. The AequoScreen(tm) cell lines will be sold as an attractive package together with the CyBi(tm)-Lumax SD.
