Patent ID: 8084239

Claim:
A method for producing a peptide-nucleic acid product comprising the steps of: a) suspending about 35.0 grams of casein, about 17.1 grams of beef peptone, about 22.0 grams of ribonucleic acid (RNA), and about 3.25 grams of bovine serum albumin in about 2.5 liters of water; b) adding about 11.75 ml of hydrochloric acid to the mixture from step a; c) autoclaving the product from step b at about 9 lbs pressure and 200-230° F. until the RNA is completely digested; d) cooling the product from step c to about 3-8° C.; e) sequentially filtering the product from step d through a 2 micron filter, a 0.45 micron filter and a 0.2 micron filter; f) diluting the product from step e with water to yield a final volume of about 5 liters; g) adjusting the pH of the product from step f to a range of about 7.3 to 7.6; h) filtering the product from step g through a second 0.2 micron filter; and i) autoclaving the product from step h at 240° F. and 20-30 pounds pressure for about 30 minutes.
