Thermo Fisher Scientific Inc., the $13 billion Waltham company focused on life sciences tools, said Monday it has agreed to sell its cell culture, gene modulation, and magnetic beads businesses to GE Healthcare, a unit of General Electric Co., for about $1.06 billion.

In a press release, Thermo Fisher said that it committed to sell these businesses to expedite approval of its pending $13.6 billion acquisition of Life Technologies Corp. by the European Commission. The Life Technologies sales agreement was announced last April. At that time, a Wall Street analyst said that the deal, when completed, would transform Thermo Fisher from the 800-pound gorilla in the lab equipment market to King Kong.

Thermo Fisher said Monday that it still expects Life Technologies transaction to close in early 2014.
