- The reaction was performed in identical cylindrical glass vials with a reaction volume of 2 ml purified AXE solution in 50 mM Tris–HCl buffer, pH 7.4, and 2 ml oil or hydrophobic substrates after vortexing. All samples were stored for 2 days before observation
- The results represent the mean ± SD over at least three replicates
