"The TASE is home to Israel's most innovative companies among them over 50 biotechnology companies and 51 dual-listed companies. The listing of Protalix, a leading company in the biotechnology sector, reflects the international leading position of the Tel Aviv Stock Exchange in the Hi-Tech and biotech industries"
