Versuchsvorschrift

To a solution containing 20.3 g (100mmol) of indole-3-pyruvic acid and 26.5 g (100 mmol) of pyridoxamine-5-phosphate in 1000 ml of distilled water buffered at pH 6.5 with 0.5M phosphate buffer and maintained at 37° C. is added 50 mg of the monoclonal antibodies prepared according to Example 15. The reaction mixture is gently agitated for 2 hours. The monoclonal antibodies are then recovered by ultrafiltration. Dialysis of the reaction mixture followed by lyophilization yields the product L-tryptophan.
