Summary
The presence or absence of human hexosaminidases A and B was studied in 105 man-Chinese hamster hybrid cell clones. The results show that these two isoenzymes behave as independent markers.
Zusammenfassung
Das Vorkommen oder Fehlen der menschlichen Hexosaminidasen A und B wurde in 105 Zellklonen aus Zellhybriden Mensch/Chinesischer Hamster untersucht. Die Ergebnisse zeigen, daß die beiden Isoenzyme sich als voneinander unabhängige genetische Marker verhalten.
