* Au/Lysozyme samples were made with the same procedure used to make Au/BSA solutions.
 +
==Procedure==
 +
* Lysozyme in powder form obtained from ___company is used to make the lysozyme stock solution.
 +
* 5mL of 70μM lysozyme stock solution was made in the following way:
 +
** 0.005g of lysozyme was weighted out
 +
** 0.005g of lysozyme was transferred to a 15ml falcon tube and mixed well with 5mL of distilled water.
 +
** See [[User:Melissa Novy/Notebook/CHEM-571/2012/10/31|Melissa's Notebook]] for calculation that stated that 0.005g of lysozyme was needed for 5mL of 70μM of lysozyme stock solution.
 +
* The HAuCl<sub>4</sub> used to make Au/Lysozyme samples was already made on [[User:Keyun Wang/Notebook/Experimental Biological Chemistry I/2012/09/05|2012/09/05]], and the concentration of the HAuCl<sub>4</sub> was 10mM.
 +
* Au/Lysozyme samples was made with mole ratios listed below:
 +
  20 - 30 - 40 - 50 - 60 - 70 - 80 - 100 - 120 - 130
 +
* Based off the calculations for Au/BSA samples, a few changes were made to calculate the amount of lysozyme and HAuCl<sub>4</sub> needed for Au/Lysozyme samples.

Purpose

  • Au/Lysozyme samples were made with the same procedure used to make Au/BSA solutions.

Procedure

  • Lysozyme in powder form obtained from ___company is used to make the lysozyme stock solution.
  • 5mL of 70μM lysozyme stock solution was made in the following way:
    • 0.005g of lysozyme was weighted out
    • 0.005g of lysozyme was transferred to a 15ml falcon tube and mixed well with 5mL of distilled water.
    • See Melissa's Notebook for calculation that stated that 0.005g of lysozyme was needed for 5mL of 70μM of lysozyme stock solution.
  • The HAuCl4 used to make Au/Lysozyme samples was already made on 2012/09/05, and the concentration of the HAuCl4 was 10mM.
  • Au/Lysozyme samples was made with mole ratios listed below: 
  20 - 30 - 40 - 50 - 60 - 70 - 80 - 100 - 120 - 130
  • Based off the calculations for Au/BSA samples, a few changes were made to calculate the amount of lysozyme and HAuCl4 needed for Au/Lysozyme samples.
  • The table below listed the initial conditions for both lysozyme and HAuCl4 both theoretically and actually:

  • The stock solutions were added with pipetman and non-sterile pipette tips. All samples were made in 10mL large test tubes. All samples were capped and wrapped in aluminum foil.
  • All samples were placed in incubator at 85°C for four hours then in room temperature to cool down.
