Objectives

  • React thiol-DNA/ThT/AuNP at 150:1 concentrations of thiol-DNA:AuNP
  • Run 2% agarose gel on thiol-DNA/ThT/AuNP synthesized on 04/23/2013
  • Take absorbance and fluorescence measurements of thiol-DNA/ThT before and after attaching AuNP

Procedures

  • New AuNP synthesized is 29.67nM with a diameter of 10nm

Previous concentrations used:

Initial Final
thiol-DNA 5.82μM 727.5nM
ThT 5μM 625nM
AuNP 19.4nM 9.7nM

To be used:

Initial Final
thiol-DNA 17.8μM 2.225μM
ThT 20μM 2.5μM
AuNP 29.67nM 14.835nM

Calculations:

Part 1: Preparing 17.8μM thiol-DNA

original concentration of thiol-DNA- 53.1μM

53.1μM (x) = (17.8μM)(500μL) x= 167.63μL in 332.37μL buffer

Part 2: Preparing 20μM ThT

original conc ThT= 5mM

5mM (x) = (0.02mM)(10mL) x=40μL in 9960μL H2O
