Microalgae are considered as a promising feedstock for the production of valuable fatty acids. In this study, individual acid profiles during growth period Chlorella vulgaris were investigated. The results showed that quantity and type acids changed with varying rates microalgal cells. Interchanging may provide some metabolic information complementary method to radiolabeling studies. For C. , t...

JL our basic science articles and two special contributions included in this issue of the Journal address some of the persistent challenges that continue to moderate the progress of radioimmunoimaging and therapy (1-6). The reports are important because of the new data they provide about current methodologies for radiolabeling antibodies for imaging and therapy. This editorial will review, and ...

Rhenium-188, obtained from an alumina-based tungsten-188/rhenium-188 generator, is actually considered a useful candidate for labeling biomolecules such as antibodies, antibody fragments, peptides, and DNAs for radiotherapy. There is a widespread interest in the availability of labeling procedures that allow obtaining 188Re-labeled radiopharmaceuticals for various therapeutic applications, in p...

UNLABELLED Small biomolecules are typically radiolabeled with (18)F by binding it to a carbon atom, a process that usually is designed uniquely for each new molecule and requires several steps and hours to produce. We report a facile method wherein (18)F is first attached to aluminum as Al(18)F, which is then bound to a chelate attached to a peptide, forming a stable Al(18)F-chelate-peptide com...

A simple and efficient method for radiolabeling preformed liposomes was developed using hepatobiliary imaging agent (99m)Tc-diisopropyl iminodiacetic acid ((99m)Tc-DISIDA). Chloroform extraction of (99m)Tc-DISIDA from aqueous solutions results in 80% radioactivity in the organic phase due to its lipophilic properties. However, with the presence of reduced glutathione (gamma-Glu-Cys-Gly), chloro...
