Italy is a very favorable situation. There are a lot of specialized institutes. A small sales force cultivating relationships with just a few key customers could easily generate several hundred kit sales a year. To a PLCSF.OB, that's significant sales.
I know nothing useful about the other covered territories.
Even with full penetration of managements estimated market of a million kits a year PLC wouldn't be a giant, but half a percent of that market would make it a going concern.
