E18.5 C57BL6 NKX2.1, FOXF1, and ACTA2 Confocal Imaging

Immunofluorescence-  NKX2.1, FOXF1 and ACTA2

 

Purpose:  Stain slides of 7µm frozen sections of C57Bl/6J mouse lung E18.5 for NKX2.1, FOXF1 and ACTA2 with antigen retrieval.

Day 1

  1. For Frozen tissue, rinse 2X in PBS, then 5 min in 4% PFA/PBS, then rinse 1X in PBS.
  2. Briefly equilibrate slides in Antigen Retrieval Buffer.
  3. Antigen retrieval, pH 6.0 (times will vary according to microwave).
  4. 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).
  5. Microwave according to instructions on microwave.
  6. Cool on countertop, 15 min.
  7. Rinse with dH2O
  8. 1X PBS, 5 min.
  9. Block in 4% Donkey serum/PBS-T, 2 hours at RT.
  10. For rabbit anti- NKX2.1 (RB TTF-1 1231, Lot# 0912A) dilute 1:1000, For goat anti- FOXF1 dil
