[Typing of gonadospecific diaphorase (DIA3) in seminal stains and esterase D typing in seminal and saliva stains (author's transl)].

1. The gonadospecific DIA3 types were traceable for 4 weeks, in some cases for 6 weeks. 2. EsD polymorphism was not demonstrable by starch gel electrophoresis in sperm, not even in sperm lysates. 3. EsA patterns showed only non-reproducible differences. 4. Because of their low concentrations, salivary esterase cannot cause errors when mixed stains are examined.
