New QC Tool for Microarray Scanners

A new quality assurance tool is a unique, solid-state diagnostic tool that ensures continued performance of microarray scanners by comprehensively testing the related optical, mechanical, and electronic systems.

LaserCheck is designed for use with the highly complex LS and LS Reloaded series of microarray scanners of Tecan Iberica Instrumentation (Barcelona, Spain). This tool operates a 45-minute, 100-point diagnostic test, using a wide spectrum fluorescent dye, which is resistant to laser bleaching, to check the multiple lasers present in the LS series scanners, and provides documented test verification in both electronic and hard copy formats.

LaserCheck can increase the efficiency of routine tests, Tecan noted, by reducing the time taken to perform them, thereby freeing resources for other activities. LaserCheck's hightened sensitivity helps users to identify and troubleshoot operational problems, giving them more confidence in the results and avoiding the false-positives or false-negatives often encountered with standard scanner routines.

Each LaserCheck plate offers unlimited reuse and requires only annual recalibration, making it an economic option for development and production facilities, where high performance and throughput requirements of scanners demand a quick and accurate quality assurance tool.
