| Make an 8% stock solution of NiCl2 in H2O; this can be stored indefinitely at room temperature. Prepare DAB + Ni by thawing a 1-mL aliquot of 0.3 mg/mL DAB solution
and adding 8 μL of 8% NiCl2 stock solution just before use. Mix by inverting the tube several times. Do not store DAB + Ni because the nickel eventually
precipitates as nickel phosphate.
