Objectives

  • Bind DNA to MB and AuNP
  • React AuNP with ethanethiol

Procedures

Part 1: Reacting DNA with MB first, followed by a reaction of the DNA-MB hybrid with AuNP

1) Prepare 727.5nm 8-repeat DNA-thiol and 800nm MB

a) 727.5nm 8-repeat DNA-thiol

(Original concentration of DNA is 53.1μM)

53.1μM(x)=(500μL)(1455nm)

x= 13.7μL in 486.3μL H2O

1455nM(x) = 727.5nm(200μL)

x= 100μL 1455nM in 100μL H2O

b) Prepare 800nm MB

(Original concentration of MB is 7.31μM)

7130nm(x) = (800nM)(50μL)

x = 5.47μL 7.31μM in 44.53 μL H2O

3) Mix 50μL 727.5nM DNA with 50μL 800nM MB

4) Hybridize by placing mixture on heat block @ 76°C for ~25minutes

5) Turn off heat block and allow cooling to room temperature

Part 2: Reacting DNA with ThT first, followed by a reaction of the DNA-ThT hybrid with AuNP

1) Prepare 727.5nM DNA (see Part 1, step 1a)

2) Prepare 800nM ThT

  • Note that the ThT prepared on 01/29/2013 assumed a 100% mass, when it was actually 75%. Use a 5mM ThT solution prepared by Dr. Miller.

5mM(x) = (5μM)(10mL)

10μL of 5mM ThT in 9990μL buffer

5μM (x) = (800nm)(1mL)

x= 160μL 5μM ThT in 840μL buffer

3) Mix 50μL 727.5nM DNA with 50μL 800nM ThT
