Sažetak

Cathepsin D was isoilated from human tissues by anticatheipsin
D antibo:dy-Serpharose 4B .chromatoigraphy. Caithepsin D,
rele1ased from the immunoaffinity column formed one precipitin
line with specif.ic antibody in immwnod:Lffusion and in immunoe1ectropholl1esis.
The isolated proteinase is shown to be prure
cathepsin D by actiivity and by inhibition with peipstatin.
The quanititative determinati.on o:f cathepsin D in human
tissue, taiken by bio.psy from sco,Uotic patients 1rl ivery small
amount, is desert.bed.
It was demonstrated that cathepsin D from human muscle
and human gingival fluid was indistinguishable in immunodiffus
ion from the human liver catheps iirl D.
