Siemens Healthcare Diagnostics last week introduced the Siemens Tissue Preparation Solution, which the company claims is the first fully automated method for isolating nucleic acids from formalin-fixed, paraffin-embedded tissue samples.
DxNA of St. George, Utah, has been awarded US Patent No. 7,993,910, "Methods and apparatus for amplification of DNA using sonic energy."
William Bickmore and Danvern Ray Roberts are named as inventors on the patent.
The diagnostics firm is offering 5 million shares with a target of $35 million in total proceeds – roughly 41 percent of the $86.3 million target the company gave when it filed to go public a year ago and 52 percent of the adjusted $67 million target it set in November.
