ABSTRACT:
The present invention relates to fluorinated surfaces which exhibit sufficient hydrophilicity and sufficient electropositivity to bind DNA from a suspension containing DNA and permit elution of the DNA from the surface. Generally, the hydrophilic and electropositive characteristics are expressed at the fluorinated surface. Preferred fluorinated surfaces of the present invention include fluorinated Al(OH).sub.3, fluorinated SiO.sub.2 and fluorinated Celite. The fluorinated surfaces of the present invention are particularly useful in processes for purification of DNA from other cellular components. In these processes, a suspension of cellular components is placed in contact with the fluorinated surface, the fluorinated surface is washed to remove all cellular components other than DNA which are bound to the surface, and the bound DNA is eluted from the surface. Lower concentrations of chaotrope in the binding buffer are needed to bind DNA to the fluorinated surfaces.
