Composition containing peptides and nucleic acids and methods of making same

In a method of preparing a composition containing peptides and nucleic acids comprising the steps of:

• forming a mixture of casein, blood albumin, beef peptone, nucleic acid and a base in an appropriate medium;
• processing the mixture at an elevated temperature and an elevated pressure;
• separating from the processed mixture components having molecular weights outside of a range from about 1-25 kDa such that the mixture absorbs light in at least two bands having maximum values at 205 nm and 260 nm;
• the improvement comprising the step of:
• further removing from the mixture components having molecular weights of <8 kDa such that the mixture absorbs light in a wavelength interval from about 200-240 nm with a maximum absorbance at 205 nm.
