APU at Uppsala University is procuring a MESO SECTOR S 600MM to replace the previous MESO QuickPlex SQ 120 model for electrocehmiluminescence (ECL) readout in the Meso Scale lab at BMC, Uppsala. The MESO SECTOR S 600MM and MESO QuickPlex SQ 120 laboratory analytical instruments are manufactured and sold solely by Meso Scale Discovery (MSD), a division of Meso Scale Diagnostics, LLC of Rockville, MD. The Imagers are compatible only with microwell plates and immunoassay kits sold by MSD and vice versa. MSD utilizes electrochemiluminescence to detect binding events on patterned arrays. There are no other technologies that enable multiplexed measurement using electrochemiluminescence for detection. And there are no other suppliers that provide an electrochemiluminescence detection system that is not reliant on beads or flow cells.
