CLEVELAND, Jan. 14, 2013 /PRNewswire/ -- ChanTest announced today the capability to perform a bioassay in conformance with current Good Manufacturing Practices (cGMP)*. The in vitro assay involves higher throughput Ussing chamber experiments for measuring inhibition of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) chloride ion channel short circuit current, a measure of chloride ion secretion. ChanTest passed its first regulatory inspection related to this cGMP bioassay at the end of last month.
In 2000, ChanTest began initiating assays related to hERG potassium channels in accordance with FDA Good Laboratory Practice (GLP) for Nonclinical Laboratory Studies (21 CFR Part 58). The new cGMP testing capability allows ChanTest to offer a unique service to the pharmaceutical and biotech industry. ChanTest will offer cGMP bioassays for release of natural products (i.e., botanicals) and any drug working via ion channels, GPCRs or transporter targets for which analytical testing is not possible.
Arthur "Buzz" Brown, M.D., Ph.D., CEO at ChanTest said, "ChanTest is extremely excited to bring this unique cGMP testing service to the pharma community. This means that we can now partner with pharma and biotech companies to bring safe medicines to market from the beginning to the very end of the drug development process."
ChanTest offers screening service with the Ussing assay for important transporters targets. Ussing experiments involve measuring electrical currents across epithelial cells under voltage clamp conditions.
