Making HAuCl4 and Lysozyme Stocks

  • Final [H+] wanted: 0.25 mM
  • Actual amount of HAuCl4: 0.04550 g
    • (slightly more water added to the volumetric flask)
  • Final [Lysozyme] wanted: 250 μM
  • Actual amount of Lysozyme:


Next, solutions were made with gold:protein ratios of 10:1 to 60:1.
