Reuters broke news of a preliminary approach by Roche, citing unnamed sources who said the deal is being held up by a disagreement about the price. If the deal goes ahead, it would represent a continuation of Roche's push to build out its sequencing unit, a strategy that has seen it acquire Genia Technologies, Kapa Biosystems and other companies in recent years.
