Abstract
PRE-TREATMENT of Seitz-type filters with serum or with digest broth will reduce, to some extent, the often serious losses of virus caused by adsorption during filtration. Solutions of gelatin have been used recently instead of serum or broth with the same object in view. Although certain advantages are claimed for the use of gelatin, for example that most samples are antigenically inert, experience has shown that losses during filtration through asbestos filters treated with this protein substance are not uniformly negligible.
