Mouse as Determined by Labeling with
DFP32 in Vivo

Rijswijk, The Netherlands.
The red cells of rats and mice were tagged in vivo by injection of diisopropylphosphorofluoridate (DFP), labeled with P32, and the disappearance
of radioactivity from the circulating red cells was determined. From the data
obtained, it is concluded that the disappearance of the red cells is linear with
time and that the red cells in both rats and mice have a true life span without
measurable random destruction.
The life span of the erythrocytes was found to be 60.0 ± 3.2 (S.D.) days
in the rat and 40.7 ± 1.9 (S.D.) days in the mouse.
Especially in the mouse the determination of the red cell life span with
DFP32 is a simple procedure.
