The life sciences company, which designs machines to speed up DNA sequencing in labs, sees net proceeds of $182.5 million, assuming the offering priced at $16 per share, the mid-point of the range.

The company plans to invest about $60-$70 million of the proceeds in its technology platform called single molecule, real-time, or SMRT technology.
