Results of anion and cation exchange column analyses of extracts of homogenates from tissues harvested following intravenous injection of [1-3H]6FDG. Extracts of homogenates revealed little evidence of charged metabolites. With the anion exchange column, A, water eluted the majority of the radioactivity indicating lack of negatively charged metabolites (e.g. phosphorylated 6FDG). With the cation exchange column, B, water eluted the majority of the radioactivity indicating lack of positively charged metabolites. Blood radioactivity was negligible at 24 h. Some error bars are too small to be visualized.
