Translocation of 32P from leaves to seeds of sunflower and associated biochemical changes in young and mature leaves during seed-filling

Acta Societatis Botanicorum Poloniae, 2014
Transport of 32P from mature leaves was studied at stage I (ray florets opening), stage II (50% florets opening) and stage III (central disc florets opening) of the capitulum in order to ascertain the capacity of developing seeds to draw metabolites ...

A biosynthetic method for the preparation of high specific activity 32P-labeled phospholipids

Journal of Lipid Research, 1976
32P-Labeled phospholipids with specific activities up to 400 mCi/mmole as well as [32P]CDP-choline were prepared by cultivation of mouse fibroblasts or mouse Ehrlich ascites cells in the presence of [32P]orthophosphate.

Synthesis of [32P]dolichyl phosphate, utilizing a general procedure for [32P]phosphorus oxychloride preparation.

Journal of Biological Chemistry, 1982
Equilibration of the phosphorus in radioactive phosphoric acid with the phosphorus in phosphorus oxychloride occurs if these compounds are refluxed together for approximately 24 h. This observation led us to develop a method for the preparation of radioactive phosphorus oxychloride on a small scale with high specific radioactivity.

Origin of phospholipids in the chick embryo during development

Journal of Lipid Research, 1965
Inorganic-32P, injected into yolks of eggs incubated to produce embryos of different ages, was incorporated into all phospholipid fractions in both whole chick embryo and embryo brain. Specific activity values compared between individual phospholipids of

Efecto del uso del suelo en las formas y disponibilidad de fósforo de un Andisol de la Meseta P’urhépecha, Michoacán

Terra Latinoamericana, 2019
Los Andisoles se distinguen por su habilidad para retener fósforo (P), lo cual restringe la productividad agrícola. Se planteó la hipótesis que la disponibilidad de P en las diferentes formas extraídas secuencialmente, variaría de acuerdo al uso del ...
