Tritium and Phosphorus-32 in High-Resolution Autoradiography.

The sensitivity of monolayers of Ilford L-4 nuclear emulsion to beta(-)-particles is approximately 0.20 grain per particle emitted for H(3), and 0.025 grain per particle for p(32). The sensitivity for thick layers is 1.3 grains per tritium beta(-)-particle emitted within the emulsion. In electron microscopic autoradiographs the maximum resolution is approximately 0.1 micron for H(3) and 0.3 mic...

The Use of Phosphorus 32 in Studies on Plasmodium Gallinaceum

The measurement of the degree of incorporation of P(32) into nucleic acids has been used as a quantitative means of studying parasite growth and development in vitro under various conditions. An extract of normal chicken erythrocytes was found to be of unique importance as a constituent of the medium, both for intact parasitized cells and for lysates of such cells. Heated normal chicken serum p...

Studies on Lateral Movement of Phosphorus 32 in Peppermint.

Auchter (1) wras the first to show that very little lateral nmovemiient of nutrient elemiients occurred in certain plants. The work of Caldwell (3) and McAMurtrey (7) also indicate(d a lack of lateral movemleint of mineral elements in the test plants used. From these studies, it seenms that there is a lack of lateral nmovement of nmineral nutrients in some plants. It was (lecidedl to test this ...
