It comprises of a cellulose-based matrix containing chemicals for cell lysis and nucleic acid preservation.   The chemicals are activated when a biological fluid contacts the surface.   An additional feature of this chemical treatment is bacterial and viral inactivation.   Not only are the biosamples protected from microbial growth contamination, but the user is also protected from any potential biohazards present in the biosample.   These features make FTA paper an ideal medium for transporting bioamples at room temperature without the requirement of a biohazard shipping label. FTA paper is a commonly used substrate for DNA storage in a number of industries such as pharmaceutics, law enforcement, agriculture and governmental regulatory agencies.   This medium has been available commercially for a number of years by Whatman Inc., who have demonstrated that DNA stored on FTA paper has a long, useful lifetime.   In fact, suitability for use of DNA recovered from up to seventeen year-old biosamples in human identification assays has been demonstrated, inarguably. and aniline dyes; or liver tumours and vinyl chloride).

It is evident acceptance was only communicated after Chernek’s death; hence the contract was terminated. What makes
