[Radioactive labeling of Blatella germanica]. 1979

R Metzger, and J Hanisch, and W Regenstein

For ecological investigations in natural populations of Blatella germanica a new method of dry incorporation of a porcelain tracer is developed. The quality of this method in contrast with other non radioactive and at present radioactive methods depends on the stable position of the tracer and the possibility of taking different marking substances for individually marking a large number of experimental animals. The identification bases on the previously investigated half-life values. The new method in combination with the recaptivate method is a good possibility to analyse a population of cockroaches.

D007553	Isotope Labeling	Techniques for labeling a substance with a stable or radioactive isotope. It is not used for articles involving labeled substances unless the methods of labeling are substantively discussed. Tracers that may be labeled include chemical substances, cells, or microorganisms.
