From: Non-enzymatic formation of isoprene and 2-methyl-3-buten-2-ol (2-MBO) by manganese

Effect of metal ions on the formation of isoprene and 2-methyl-3-buten-2-ol (2-MBO). Data are mean ± SE (n = 3). Two mM DMADP and 20 mM metal ions were reacted at 40 °C for 1 h at pH 8.5 and the head space gas was analyzed by GC. Formation rate of isoprene and 2-MBO was calculated by relative proportion against the peak area of standard isoprene gas.
