Figure 7. Mouse hepatic free BMAA after feeding.

Figure 7

GC-MS m/z chromatograms of stable isotope dilution assay of mouse liver. H3-BMAA (m/z 116 and 245, arrows) along with its deuterated standard (m/z 119 and 248, arrows) were detected in the extractable fraction, also called free BMAA, in mice fed BMAA (A) but none of the mice fed control diet that lacked BMAA (B). Scattergram shows average values of triplicate determinations of hepatic free BMAA as well as mean ± SEM for all eight mice fed BMAA (C). No detectable free or protein-associated BMAA was detected in any of the six mice fed control diets.
