The globalization and sustained growth of the biotechnology market has brought the issue of biological packaging to the fore, particularly for those companies invested in cell and tissue bioproducts, such as engineered tissues and cells used for cell therapy. Biological packaging can be defined as the sum total of the physical device, temperature regulating and monitoring systems, type of preservation solution, and storage protocol(s) necessary to maintain cells or tissues in a “state of suspended animation” during transport or storage. The ideal biological package provides for the transport of cells and tissues throughout the global marketplace while maintaining both the viability and the function of the biological system at levels equivalent to those measured prior to shipment. Cells and tissues are currently shipped and stored under hypothermic (4–8ºC) or cryopreserved (–80 to –196ºC) conditions. These two processes have remained relatively unchanged over the past several decades, limiting their utility in the storage of modern bioproducts. However, recent evolutions in biological packaging have begun to provide scientific and financial benefits to researchers, clinicians, and corporate entities…

Within the biopharmaceutical industry, mammalian cell culture is extensively used to manufacture a various biopharmaceutics uncluding antibodies, interferons, hormones, crythropoietin, clotting factors, immunoadhesins, and vaccines. The market for monoclonal antibodies (MAbs) alone is expected to grow 30% a year and reach sales of nearly $6.5 billion in 2004. The vast majority of these biotherapeutics are secreted glycoproteins obtained from mammalian cell lines such as: Chinese hamster ovary (CHO), human embryonic kidney 293 (HEK-293 or 293). NS0, and baby hamster kidney (BHK). As is the goal with most commercial products, biotechnologists strive to generate these valuable proteins in the highest yields possible in order to utilize mammalian bioreactor facilities efficiently…
