Introduction of Radioactive Tracers into Antisera

Radioactive Tracers in Biology

Everybody talks about the atom, but few have more than a Sunday supplement knowledge of the simpler aspects of nuclear phenomena. The author, M.D. and Ph.D., and a member of the staff at Brookhaven, treats the story of the atom from its earliest historical conceptions to its possibilities in future war and peace. The style is of the simplest; no previous familiarity with mathematics or physics ...

Flux measurements of cations using radioactive tracers.

Standard procedures for the tracing of ion fluxes into roots of plants are described here, with emphasis on cations, especially potassium (K(+)). We focus in particular on the measurement of unidirectional influx by use of radiotracers and provide a brief introduction to compartmental analysis by tracer efflux (CATE).

Studies on Embryonic Induction using Radioactive Tracers

T H E nature of the agent which brings about induction during the early development of vertebrates has been extraordinarily difficult to determine. As yet we are not even certain whether there is a passage of a comparatively massive quantity of material from the organizer into the reacting competent tissue, as is probably most usually assumed, or whether the action is primarily located at the s...

Movement of radioactive tracers across squid axon membrane.

The measurement of blood flow in humans using radioactive tracers.

Since the first description of the movement of blood around the body by William Harvey, the accurate measurement of blood velocity has provided a major challenge for medical science. This review looks at the contribution made by techniques using radioactive tracers. Initially consideration is given to the fundamental problem of how to measure the amount of radiotracer in an organ with sufficien...
