Incubation of 3-day-old rat brain with L-[methyl-3H]methionine resulted in the rapid labeling of low-molecular-weight cytoplasmic RNA. Electrophoresis in 15% polyacrylamide gels provided evidence for the methylation of precursor tRNA molecules, and high-performance liquid chromatography demonstrated N2-methylguanine to be the predominant methylated base formed during the first 2 min of labelling.
Various metal nanoparticles including base metal were produced by a brief accelerated electron beam irradiation of 1-alkyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)amide room-temperature ionic liquid without a stabilizing agent, which is usually employed so as to prevent aggregation.
Platelet activating factor obtained from antigen-stimulated rabbit buffy coat leukocytes containing 10% IgE-sensitized basophils was shown by gas-liquid chromatographic and mass spectrometric analysis of products after acetolysis and by base and acid hydrolysis to be acetyl-alkylglyceryl phosphorylcholine. The alkyl side chains were composed of octadecyl (greater than 90%) and hexadecyl (less t...
