Immunofluorescence labeling of tissue specimens was performed by fixing tissue sections or cells in 4% PFA/PBS and blocking in 1% BSA (or permeated with 0.1% Triton X-100/PBS for 10 min for GORAB staining) prior to incubating with primary antibodies. The following primary antibodies were used: GORAB, 1:500 (Proteintech); AQP5, 1:50 (A4979, MilliporeSigma); SFTPC, 1:250 (ab40879, Abcam); VCAN, 1:200 (ab1032, MilliporeSigma); VIM, 1:200 (ab92547, Abcam); F-actin, 1:50 (ab205, Abcam,); VCL, 1:100 (ab129002, Abcam); SCGB1A1, 1:200 (sc-365992, Santa Cruz); ACTA2, 1:500 (a2547, MilliporeSigma); CDH1, 1:100 (BD-610182, BD biosciences). AlexaFluor-conjugated secondary antibodies (1:250) were from Life Technologies (Thermo Fisher Scientific). Sections were sealed in mounting medium with DAPI (Vector Laboratories, Burlingame, CA). TUNEL staining was performed according to manufacturer’s instructions (DeadEnd Fluoremetric, G3250, Promega, Chicago, IL). Images were acquired by Nikon 80i fitted with a Nikon DS-Qi1Mc camera and processed with Photoshop 5.5 CS (Adobe, San Jose, CA).

Immunofluorescence labeling of tissue specimens was performed as
described previously (Dai et al., 2013 (link)).
Cells were fixed in 4% PFA and blocked in 1% BSA prior to
incubating with primary antibodies. The following primary antibodies were used:
GORAB, 1:500 (Proteintech); KRT14, 1:1,000 (Covance); KRT1, 1:2000 (Roop et al.,
1987); KRT17, 1:200 (Abcam); LOR, 1:500 (Covance); NGFR, 1:200 (Promega); LEF1,
1:100 (Cell Signaling, Danvers, MA); acetylated α-tubulin, 1:600
(Sigma); γ-tubulin, 1:500 (Abcam); ARL13B, 1:100
(#73–287, NeuroMab); lectin Helix pomatiaagglutinin (HPA), 1:1,000 (Invitrogen); Golgin97, 1:1,000 (Molecular Probes),
and Ki67, 1:1000 (BD Pharmingen). AlexaFluor-conjugated secondary antibodies
(1:250) were from Life Technologies. Sections were sealed in mounting medium
with DAPI (Vector Laboratories). TUNEL staining were performed with DeadEnd
Fluorometric TUNEL System (Promega). Images were acquired by Nikon
80i fitted with Nikon DS-Qi1Mc camera and processed with
Photoshop 5.5 CS.

Western Blot Quantification of Protein Targets

Protein was extracted in cold RIPA lysis buffer (50 mM Tris-HCl pH 7.4,
150 mM NaCl, 1% Triton X-100, 1% sodium deoxycholate, and
0.1% SDS) supplemented with proteinase inhibitors. Tissue or cell
lysates were cleared and separated by 10% SDS-PAGE and transferred to
polyvinylidene fluoride (PVDF, Millipore) or Hybond nitrocellulose (GE
Healthcare) membranes, following standard procedures. Blots were probed with the
primary antibodies which were then detected with HRP-conjugated secondary
antibodies (BD biosciences) and SuperSignal substrates (Thermo Scientific).
Enhanced chemiluminescent (ECL) substrate (Pierce, Rockford, IL USA) and
CL-XPosure film (Thermo Scientific) were used for detection. The following
primary antibodies were used: GORAB, 1:1,000 (Proteintech); β-actin,
1:1,000 (Santa Cruz); GLI1, 1:250 (clone V812, Cell Signaling); GLI3 (1
µg/ml, Cell Signaling). Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)
or β-actin was used as a loading control. Quantification was performed
with densitometry and ImageJ software (1.43u, NIH).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
