La Vista, NE – The United States Patent Office granted U.S. Patent No. 9,926,590 today to Streck, Inc. The patent is directed generally toward a direct-draw blood collection tube for the stabilization of a patient blood sample and to subsequent downstream isolation of nucleic acids for analysis.

The patent joins Streck’s growing intellectual property portfolio covering stabilization products, which may find particular use in noninvasive prenatal testing or liquid biopsy applications.

“Protecting our valuable intellectual property demonstrates Streck’s commitment to and investment in developing and manufacturing quality control and diagnostic products for the clinical and research laboratories,” said Connie Ryan, President & CEO, Streck, Inc.  “It is Streck’s responsibility, in the face of an ever changing marketplace, to protect itself and to secure a path for continued growth.”

Presently, Streck offers several direct-draw blood collection tubes for the stabilization of patient samples, facilitating transport to remote clinical laboratories for nucleic acid isolation and analysis, among them:

  • Cell-Free DNA BCT® and Cell-Free DNA BCT® CE help prevent the release of genomic DNA, allowing isolation of high-quality cell-free DNA for a wide range of downstream applications commonly used in clinical research studies, drug discovery and diagnostic assay development. The tubes reduce the need for immediate plasma preparation due to its unique stabilization properties. Cell-free DNA is stable for up to 14 days, and circulating tumor cells are stable for up to 7 days at room temperature, allowing convenient sample collection, transport and storage.

 

  • Cell-Free RNA BCT® and Cell-Free RNA BCT® CE help prevent the release of cellular RNA, allowing isolation of high-quality cell-free RNA for a wide range of downstream applications commonly used in clinical research studies, drug discovery and diagnostic assay development. Cell-free RNA is stable up to 7 days at room temperature, allowing convenient sample collection, transport and storage.
