Bristol-Myers to buy Medarex for $2.4 billion

Medarex has developed so-called "transgenic" mice with human immune systems that are able to generate fully human antibodies that can be used as drugs.

"The premium is not out of whack when you look at the scarcity value of this technology and the appetite for biotech companies right now," a source familiar with the deal told Reuters. "It's a small deal in size but a large deal in terms of the potential scope they gain with this science."
