Entry title

  • Repeat Gel Electrophoresis on same samples as 4/12/13 (Stained in ethidium bromide for too long
  • Bind AuNP to DNA-thiol hybrid

Procedures

Part 1: Repeating Gel Electrophoresis

  • Prepare samples the same way

Part 2: Reacting AuNP with DNA-thiol

1. Mix 250μL 2.5μM ThT/727.5nM thiol-DNA synthesized 04/05/2013 with 250μL 4% TEA containing 100mM DTT

2. React 10 minutes

3. Extract DTT using 4 2mL aliquots of ethyl acetate. DTT partitions into ethyl acetate and DNA partitions into aqueous phase

4. Mix 232.4μL ThT/thiol-DNA with 232.4μL AuNP and 35.2μL sodium citrate buffer
