ObjectivePrepping stock solutions for use in making AuNP fibers with lysozyme for other researchers to use. DescriptionTarget Concentrations Based on the total reaction volume that the class will be using and the final concentrations that will be in each reaction volume, I have determined that the following HAuCl4·H2O and Lysozyme masses are appropriate for today's stock solutions. Stock solutions
Actual Concentrations The actual masses are different from the target masses. The concentrations shown below reflect the actual concentrations made for the stock solutions. I used a 50 mL volumetric flask to make the gold stock solution and a 100 mL volumetric flask to make the protein solution. In each case I used HPLC-grade water. Stock solutions
Directions for making samples Note: The final concentration of gold should be 0.25 mM and the final concentration of lysozyme should be 5.556 μM. This gives a Au:lysozyme ratio of 45, which should yield fibers.
