Confocal Imaging of Donor 16171.B06 Containing an ABCA3 Homozygous Missense Mutation for SFTPC, KI67, and ACTA2

Confocal Imaging of Donor 16171.B06 Containing an ABCA3 Homozygous Missense Mutation for SFTPC, KI67, and ACTA2

Immunofluorescence- SFTPC, Ki-67and ACTA2

 

Purpose:  Immunofluorescence on slides of 5µm paraffin sections of human lung containing ABCA3 homozygous missense mutations  SFTPC, Ki-67and 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. 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 SFTPC (RB 458 in House, BL 3-23-11) dilute 1:500, For mouse anti-Ki-67 (55603, BD Biosciences, Lot# 6251774) 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-SFTPC), Goat Alexa Fluor 568 anti-mouse IgG1 (A21124, Lot# 1600878, for anti-Ki-67) at 1:200, Donkey Alexa Fluor 647 anti-mouse IgG (A31571, Lot# 1549801, anti-ACTA2) at 1:200, in blocking buffer. Spin down in µfuge for 20 min, apply to tissue and incubated at room temperature for 1 hour.
  1. Rinse in PBS-T 3X, 5 min.
  2. Dilute DAPI 1:2000 and apply to slides for 15 min.
  3. Wash in PBS-T 3X, 5 min.
  4. Rinse slides in 0.1M PB, 3X, 5 min.
  5. Add 1 drop of Prolong Gold anti-fade mounting medium (P36930).
  6. Coverslip with Gold Seal Coverslip (Cat# 3422 Electron Microscopy Sciences, 22 X 22 mm).
  7. Allow Prolong Gold to cure overnight at room temp in light sealed box.
  8. Store slides in light sealed box @ 4o
