Objective

Conductivity of AuNP III

To run the conductive plates made on 10/12/11 to determine the conductivity of AuNP.


Fluorophore

To make a labeled cysteine fluorophore.

Description

Fluorophore

  1. Combine 2 mg of 5-iodoacetamido fluorescein (5-IAF) with excess cysteine (0.39 mg) in 3.95 mL of 50 mM Tris buffer (pH 7.5).
  2. Vortex to mix.
  3. Wrap reaction tube in foil and allow reaction to proceed for 2 hr.
  4. Add 100 μL of dithiothreitol (DTT)

Data

Conductivity of AuNP II

The Pd plates broke off of the Teflon plate, so the test was not conducted.
