Abstract
A process for purifying DNA comprising binding the DNA to a silicate compound in the presence of water, low salt buffer, or physiological buffer and eluting in the bound DNA by heating in a low salt buffer, a physiological buffer, or water. The silicate compound is prepared by reacting SiCl.sub.4 with a molar percentage of BCl.sub.3 of about 33.5%, 55.6%, or 83.3%, with a molar percentage of PCl.sub.3 of about 50.0%-83.3%, or with a molar percentage of AlCl.sub.3 of about 9.1%; cooling the reaction mixture; adding water until the evolution of gas is complete; and recovering the compound.
