Compositions of stabilized DNA for coating microprojctions

摘要

The present invention provides methods and compositions for stabilizing dried nucleic acids with carbohydrates such as non-reducing sugars, polysaccharides, and reducing sugars. Preferably, the stabilized nucleic acids are coated on a microprojection member for transdermal delivery. The invention further provides compositions and methods that involve the use of DNase inhibitors to stabilize dried nucleic acids delivered directly into bodily tissues.
