3 Year Human Lung HOPX, ABCA3, and ACTA2 Confocal Imaging

3 Year Human Lung HOPX, ABCA3, and ACTA2 Confocal Imaging

  Donor Tissue Kindly Provided by Dr. Gloria Pryhuber from the University of Rochester Medical Center

Pryhuber_Lab

Immunofluorescence- HOPX, ABCA3, and ACTA2

 

Purpose:  Stain slides of 5µm paraffin sections of human lung received from the HTC for HOPX, ABCA3, and ACTA2 with antigen retrieval.

Day 1

  1. Paraffin sections are placed at 60oC for 2 hours to overnight 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 anti-HOPX (SC-30216, Lot # C2212, Santa Cruz) dilute 1:200, for mouse anti-ABCA3 (WMAB-17G524, Seven Hills Bioreagents) dilute 1:100, for mouse anti-ACTA2 (α Smooth muscle actin, A5228, Sigma) dilute 1:2000 in blocking buffer. Spin down in µfuge for 10 minutes and incubate on tissue overnight @ 4oC.

Day 2                                                                                                               

  1. Rinse slides in PBS-T 3X, 5 min.
  2. Apply secondary antibody, Goat Alexa Fluor 488 anti-rabbit IgG (A11034, Lot# 1298480, for anti- HOPX), Goat Alexa Fluor 568 anti-mouse pig IgG2B (A21144, Lot# 1584300, for anti-ABCA3) at 1:200, Donkey Alexa Fluor 633 anti-mouse IgG2A (A21136, Lot# 1345055, ACTA2) at 1:200, in blocking buffer. Spin down in µfuge for 10 min, apply to tissue and incubated at room temperature for 1 hour.
  3. Rinse in PBS-T 3X, 5 min.
  4. Dilute DAPI 1:2000 and apply to slides for 10 min.
  5. Wash in PBS-T 3X, 5 min.
  6. Rinse slides in 0.1M PB or TB, 3X, 5 min.
  7. Add 1 drop of Prolong Gold anti-fade mounting medium (P36930).
  8. Coverslip with Gold Seal Coverslip (Cat# 3422 Electron Microscopy Sciences, 22 X 22 mm).
  9. Allow Prolong Gold to cure overnight at room temp in light sealed box.
  10. Store at 4oC until imaging.
