The concentration of Free- and Pro-BMAA from each tissue in the CG and TG. BMAA was extracted from four different tissues, muscle, liver, brain and eye, of both chicken groups CG and TG. “Number” indicates the number of biological replicate accumulating BMAA. BMAA concentrations are calculated from the tissue containing BMAA and expressed as µg BMAA/g DW ± SE. Free-BMAA, free form of BMAA; Pro-BMAA, protein-associated form of BMAA; CG, control chicken group; TG, treated chicken group; NQ, non-quantifiable.
