By margarita Snegireva. Roche Holding AG raised its bid up to $3.4 billion to take over Ventana and thus overcame its resistance.
Roche said on Tuesday it would increase the tender offer for all outstanding Ventana Medical Systems Inc shares to $89.50 per share in cash, from $75 per share.
Ventana had repeatedly rebuffed Roche's original bid, calling the offer grossly inadequate, but agreed to open its books to the Swiss company in November.
