用32P示踪法研究昆明市水土流失的规律

open access: yesShuitu Baochi Xuebao, 2002
应用32P研究山地水土在不同时间、坡度、方向、深度、距离的吸收和分布规律。结果表明:1g山地土壤对32P的吸收随着深度、距离的增加而减小。土壤对32P的吸收率的最大距离为3470.7969×10-5%,最小为1.2097×10-5%;最大深度为2407.9855×10-5%,最小为0.4752×10-5%。在坡度上,磷的吸收率呈波形变化,即在15°~30°,50°~80°时随坡度的增加而减小,在30°~40°时无明显变化,在40°~50°时随坡度的增加而增加。32P的吸收率与距离、坡度、方向呈显著负相关。

Determination of mevalonate in blood plasma in man and rat. Mevalonate “tolerance” tests in man.

open access: yesJournal of Lipid Research, 1979
A method is described for the determination of mevalonate in ultrafiltrates of blood plasma. The method depends on the phosphorylation of mevalonate with [gamma-32P]ATP and mevalonate kinase to 5-[32P]phosphomevalonate, and the subsequent isolation of ...

Purification and characterization of a protein-tyrosine kinase encoded by the Abelson murine leukemia virus [PDF]

open access: yes, 1985
Sequences termed v-abl, which encode the protein-tyrosine kinase activity of Abelson murine leukemia virus, have been expressed in Escherichia coli as a fusion product (ptabl50 kinase).
