Preservation of Biological Materials at Room Temperature

详细技术说明

OverviewAuburn University is seeking licensees for technologies relating to the isolation and reversible preservation of a range of biological materials. Acacia gum, or gum arabic, is a natural sap that has been widely used since ancient times and is currently manufactured in multi-ton quantities for use in the food and allied industries. This entrapment process occurs at room temperature and can last for an extended period of time at room temperature with minimal damage to the specimen. The viable biomaterials are released from the polymer system by the application of water. This system is compatible with many biological samples including proteins, DNA, receptors, antibodies, antigens, bacteria, mammalian cells, cell surfaces, and tissues. Potential applications for this technology include:· Preservation and shipment of bacterial cultures and bodily fluids (e.g., blood, semen)· Medical application in surgery, wound healing and drug delivery· Biodegradable packaging· Forensics

*Abstract

Advantages

· Preservation process is simple and rapid, which lowers labor and costs

· Preservation can last for an extended period at room temperature, eliminating need for  expensive cryogenic storage; longer preservation times achievable through refrigeration

· Entrapment can be reversed by dissolution in water

· Eliminates traditional preservation steps that can damage biological samples

· Suitable for use in the field

· Naturally occurring polymer that is biodegradable and non-toxic

· Resistant to almost all organic solvents and most acids
