To separate the racemate (R,S)-cysteine, the racemate is condensed in an inert solvent with an enantiomerically enantiomeric monosaccharide of the group of aldoses having 4 to 7 carbon atoms to form the corresponding 2-substituted thiazolidin-4-carboxylic acid and the mixture of diastereomers obtained separated from each other. Subsequently, the isolated unitary diastereomers are reacted in an ine...

Double-stranded RNA synthesized using native human DNA as template is found to be an excellent interferon inducer with low toxicity in spite of homologous native to host cell. It is produced by reacting ATP, GTP, CTP and UTP with one another in the presence of a native human DNA as template by the catalytic action of an active RNA polymerase to form RNA and subjecting the resulting RNA to annealin...

A device wherein a fine-mesh, water-permeable suitable material (7) is placed in front of the spout (8, 12) in such a way that this sieve material acts in the manner of a filter when the coffee is poured out.
