The objective is to develop approaches are sought for sample preservation of nucleic acids from blood products or other sample for storage at room temperature conditions. The goals of the project are to: 1) determine preferable tissue for nucleic acid archiving; 2) investigate sample collection protocol, processing, of the selected tissue; and 3) initially define key potential aspects of storage conditions for preservation of nucleic acids. In addition, we will develop a completely integrated ambient temperature workflow from collection, transport to storage to avoid any cold-chain handling. This complete ambient workflow can be achieved through the integration of advanced thermo-stability products currently in Biomatrica's product development pipeline. The overall objective is the development of workflow which protects nucleic acids, in particular RNA from degradation during collection to sample archiving and determine its feasibility for large scale implementation.

Whole blood remains the cornerstone specimen type used in molecular analysis. Changes in the DNA, RNA, protein, peptide, metabolic, and blood cell analyte levels during pre-analytic specimen handling between collection and eventual molecular analysis impacts testing accuracy and delegitimizes any conclusions drawn from the results. The specific aim of this research is to develop stabilized blood collection devices which effectively preserve analytes at their collection levels, and allow for cold-chain independent shipping and storage. It accomplishes this through the utilization of biostability compounds which stabilize and protect the analytes. What is unique and noteworthy about our proposal is that these particular biostability compounds not only protect soluble analytes such as plasma proteins, but appear to act on the entire cellular fraction, including whole cells and the analytes associated or contained within them. In essence, the biostability compounds arrest the entire blood specimen in its post-collection state, and in a form which is compatible with all downstream molecular analysis. The proposed research will result in the, selection of performance-validated biostability compounds which can be incorporated into standard blood collection tubes or self-draw blood collection devices.

The projects objective is the development of a scalable all ambient temperature biological sample workflow preserving the nucleic acids for molecular analysis. This ambient workflow can be developed for large scale blood collection, transport and long-term archiving without the use of costly and unreliable cold-chain management, using commercially available biopreservation products. Since the completion of the human genome project in 2001, nucleic acid (DNA and RNA) based analysis has proven to be the most powerful diagnostic tool currently available to create actionable prediction of human health and understand and prevent disease development. The complexity of the human genome requires large sample populations to increase the predictive value of genetic analysis. Large scale archiving of population and/or patient specimens is the key to create this knowledge base. The pioneering work of Biomatrica over the past decade in the field of chemical biomaterial preservation at room temperature has allowed low cost alternatives to unreliable cold chain management. In Phase I we successfully demonstrated the power of chemical ambient preservation of nucleic acids throughout the workflow from blood sample collection and transport to the reliable storage of nucleic acids. We demonstrated that a) diagnostic analysis can be performed after storage in the ambient biopreservation products, b) the integrity of the DNA and RNA are pristinely maintained using ambient preservation c) the workflow is scalable from collection to archiving at lower costs and higher reliability than the current cold chain-based workflow. The Phase II development will result in the integration of proven commercial products into a highly scalable process, with the integration of automation equipment, the establishment of Standard Operating Procedure (SOPs) and an optimized workflow that reduces operational costs. The automated methods can be directly implemented for blood sample processing and archiving of nucleic acids in a routine setting.
