Japanese scientists have used a highly sensitive and accurate analytical method to determine the quantity of free branched amino acids (BCAAs) in a single fruit fly.

Fruit flies are a valuable organism in biological research, and particularly in the areas of genetics and developmental biology.  However, as these creatures are small, analysing the metabolites in its body is difficult, and generally a large sample pool is required.  However, this means that small individual distinctions are lost and the fly’s aminogram is equalised.

By using liquid chromatography-inductively coupled plasma-mass spectrometry (LC-ICP-MS) with pre-column derivatisation with a metal tag reagent, Daigo Iwahata and colleagues managed to accurately analyse the quantity of free BCAAs in a single fruit fly.
