Material

  • TNT wash buffer: 0.1M TRIS-HCL, pH 7.5

0.15M NaCl 0.05% Tween20

  • TNB buffer:

a) for blocking: 0.1M TRIS-HCL, pH 7.5 0.15M NaCl 20% goat serum

b) for diluting the AB: 0.1M TRIS-HCL, pH 7.5 0.15M NaCl 10% goat serum

  • quenching solution (QS): 3% H2O2 in PBS


Procedure

  1. wash once for 5 min @ RT with TNT
  2. quench for 15 min @ RT with QS
  3. wash once again for 5 min @ RT with TNT
  4. block for 30 min in TNB-20% GS@ RT
  5. primary AB:
    1. supernatant of HC: use pure
    2. purified AB: dilute 1:500in TNB-10% GS
  6. centrifuge for 10 min @ 13k
  7. incubate the primary AB o/n at 4ºC
  8. wash slides 3 times for 5 min @ RT
  9. dilute the HRP-AB 1:1000 in TNB-10% GS and centrifuge for 10 min @ 13k
  10. incubate the HRP-AB for 2 hours @ RT
  11. wash slides 3 times for 5 min @ RT with TNT
  12. dilute the Thyramide stock 1:50 with Amplification diluent
  13. incubate 150 µl per slide of the Thyramide dilution for 3- 10 min (best: 6 min)
  14. wash 3 times for 5 min @ RT with TNT
  15. add Hoechst 1:1000 in TBS/ Tween for 10 min @ RT
  16. wash once for 5 min @ RT
  17. mount
