Somaclonal variation in the qualitative aspect was relatively low (8%). However, variation in quantitative terms was high and in 10% of the calli a protein concentration six times higher than in stems was observed. These results indicate for the first time the possibility of applying tissue culture for the production of mistletoe protein extracts with increased antitumor/immunomodulatory properties. © 2002 by The Haworth Press, Inc.
