The European Union gave conditional approval to the purchase of Carlsbad-based Life Technologies Corp. by Thermo Fisher Scientific Inc.

Waltham, Mass.-based Thermo Fisher will be required to sell its businesses producing and supplying media and sera for cell culture, gene silencing products and polymer-based magnetic beads as part of what EU regulators said was an effort to “preserve competition and innovation” in the life sciences industry.

The $13.6 billion deal for Life Technologies, which makes products for genetic analysis, diagnostics and mapping, was approved by Life Technologies stockholders in August and is still awaiting U.S. regulatory approval.
