Illumina Inc. wasted no time in returning to the M&A front, closing the acquisition of Fluent Biosciences Inc. on July 9 with cash on hand, just a fortnight after freeing itself of Grail Inc. Fluent’s single-cell analysis technology expands Illumina’s presence in the life sciences, possibly marking a turn away from the diagnostics focus that led to the Grail debacle. The acquisition price was not disclosed.
