Stock Solution Preparation

1. Prepare 100 mL 2.5 mM HAuCl4

  • 2.5 mM HAuCl4 * 14307 g HAuCl4 / mol * 100 mL = 0.085 g HAuCl4
    • 0.08533 g was the final amount weighed
  • Add 0.08533 g HAuCl4 to a volumetric flask and dilute to 100 mL with deionized H2O
    • Monika prepared a total of 100 mLs HAuCl4 for both groups.

2. Prepare 50 mL 20 μM Lysozyme

  • 20 μM Lys * 340 g Lys /mol * 50 mL = 0.014 g Lysozyme
    • 0.01417 g was the final amount weighed
  • Add 0.014 g Lys to a volumetric flask and dilute to 50 mL with deionized H2O
