Immunofluorescence-NKX2.1, TP63 and KRT5

 

Purpose:  Immunofluorescence on slides of human lung  from the HTC for NKX2.1, TP63 and KRT5 with antigen retrieval.

Day 1

  1. Paraffin sections are placed on slide warmer for 1 hour to melt paraffin.
  2. Paraffin sections are then placed in xylene 3X for 10 minutes each, followed by 3X in 100% ETOH for 3 minutes each, 95% ETOH for 3 minutes each, and 70% ETOH for 3 minutes each. Slides are then placed in 1X PBS for 5 minutes to completely rehydrate tissue.
  3. Briefly equilibrate slides in Antigen Retrieval Buffer.
  4. Antigen retrieval, pH 6.0 (times will vary according to microwave).
  5. 10 mM sodium citrate, pH 6.0, and heat in a microwave at 96oC. *We usually do a series of three runs (6-7 minutes each run) to equal the time/temp because of evaporation (refill coplin jars with dH2O).
  6. Microwave according to instructions on microwave.
  7. Cool on countertop, 15 min.
  8. Rinse with dH2O
  9. 1X PBS, 5 min.
  10. Block in 4% Goat serum/PBS-T, 2 hours at RT.
  11. For mouse anti-TP63 (CM163A, lot # 102214, Biocare) dilute 1:100, For guinea pig anti-NKX2.1 (G237, Bl. 8/25/11) dilute 1:200 for rabbit anti-KRT5 (PRB-160P-200, Lot# D13DF01179, Biolegend) Dilute 1:100 in blocking buffer. Spin down in µfuge for 10 minutes a
