All Quansys Q-Plex™ Multiplex and Singleplex assays require the use of the Q-View™ software to read and interpret the test results. A fully-functional, free trial version of the software is available to download, install, and use to analyze your first kit(s). At the end of the trial period, a purchased license is required to continue the use of the Q-View software.
Q-Plex arrays are developed and optimized to work with Q-View imagers. Quansys does not guarantee the results obtained from other imagers and not all imagers are compatible with Quansys Q-Plex arrays.
