Description

It has been suggested that the rhodanine demonstrates the protein to which the copper binds rather than the copper itself. This kit is designed to identify copper deposits, such as in Wilson’s disease, left in the liver.

Protocol

     Things to do before staining: Prepare Working Rhodanine Solution

    • Shake Rhodanine Stock Solution
    • Mix Rhodanine Stock Solution 4ml with  Acetate Buffer Solution (pH 8.0) 46 ml

     Procedure

  1. Deparaffinize in xylene I for 6 minutes and II for 6 minutes.
  2. Rehydrate
    • Ethanol 100% (2 minutes)
    • Ethanol 100% (2 minutes)
    • Ethanol 95% (2 minutes)
    • Ethanol 95% (2 minutes)
    • Ethanol 70% (2 minutes)
  3. Rinse in DI water (2 minutes).
  4. Stain in Working Rhodanine Solution (three options, please only choose one): 1) at 60°C for 1-2 hours, or 2) at 37oC for 18 hours, or 3)   Microwave Modification: Place slides in a plastic Coplin jar containing Working Rhodanine Solution and microwave for 6 minutes at 70°C.
  5. At the end of incubation (for both oven and microwave), to avoid unwanted slide precipitate, pour off warm Working Rhodanine Solution into a second Coplin jar, reserve and set aside.
  6. Rinse slides well in 3 changes of Acetate Buffer Solution (pH8.0) for 1 minute each.
  7. Check positive control slide microscopically to determine adequate copper/reddish brown development. Return slides to reserved Working Rhodanine Solution if additional incubation is required (repeat step 4, 5 and 6).
  8. Stain in Mayer Hematoxylin Solution for 5 minutes.
  9. Rinse in tap water, 2×2min.
