Abstract

Autoradiography using high specific activity tritiated thymidine (40-60 curies/millimole) and nuclear track emulsion impregnated with a liquid scintillator provides a very rapid method to determine labelling index and growth fraction of cell suspensions. Low temperature (-20.degree. to -85.degree. C) emulsion exposure for 20 - 60 minutes is sufficient for excellent labelling, thus allowing rapid clinical decision making. Exposure times for research techniques requiring very low energy labelling can be considerably shortened, e.g., from 6 months to 2 weeks or less. This technique therefore has broad applicability to biology and medicine.
