PALO ALTO, Calif.--Dispelling industry rumors that Molecular Applications Group is up for sale, Debbie Yu, acting CEO, said the company is seeking partnerships, but not a buyer. "MAG is definitely not on the block, but we are pursuing conversations with a number of strategic players because it is a cornerstone of our business plan to do that," Yu said. Rumors about the company's financial health heated up recently after John Andrews, executive vice-president and chief operating officer, departed from the company.
