For proximity ligation assay (PLA), the cells were seeded on cover slips and fixed either with (i) 4% formaldehyde for 10 min at 37 °C and then washed twice with 0.02% PBS-T and permeabilized using 0.5% Triton X-100 in PBS for 5 to 10 min at RT or (ii) chilled methanol:acetone 1:1 for 10 min and dried at RT for 3 h (in the case of T47D cell line). Afterward, the cells were incubated with blocking buffer (Sigma–Aldrich—Duolink) for 1 h at 37 °C in a wet chamber. Primary antibodies against AGR2 (1:250; Abnova), PDIA3 (1:500; Abcam), and PDIA6 (1:250; Novus Biologicals) were then incubated in Ab diluent (Duolink) at 4 °C overnight. The PLA was performed with the Duolink In Situ Red Kit Mouse/Rabbit (Sigma–Aldrich) according to the manufacturer's instructions. Anti-mouse MINUS and anti-rabbit PLUS PLA probes (Sigma–Aldrich) were used. Coverslips were mounted with Vectashield mounting medium, and images were acquired by Olympus BX41 microscope using a 40× objective. Images were analyzed with CellSens software (Olympus).

The experiment was performed according to Wang et al. (2015) using the Duolink In Situ Red Kit Mouse/Rabbit (DUO92101; Sigma-Aldrich). Briefly, subsequent to standard dissection and fixation, L3 larvae were blocked for 1 h in PBT containing 5% NGS. Next, samples were incubated with rabbit-α-Cpx (1:500) and mouse-α-Brp (1:250) antibodies overnight at 4°C. After three 10–min washing steps using 0.05% PBT, the samples were incubated for 2 h at 37°C with 1:5 dilution of α-rabbit PLUS (DUO92002; Sigma-Aldrich) and α-mouse MINUS (DUO92004; Sigma-Aldrich) PLA probes, which were added to 5% NGS containing blocking solution. Alexa Fluor 488–conjugated α-HRP antibody (1:250) was added to the mixture in order to enable visualization of neuronal membranes. Following two 5-min washes with Wash buffer A, samples were treated with Ligation solution (1:40 dilution of Ligase in Ligase buffer) for 1 h at 37°C. Again, samples were washed twice for 2 min with Wash buffer A. Next, the samples were incubated in Amplification solution (1:80 dilution of polymerase in amplification buffer) for 2 h at 37°C. After two 10-min washing steps using Wash buffer B, samples were washed twice in 0.01× Wash buffer B and kept in Vectashield-H1000 overnight at 4°C before mounting.

The in situ proximity ligation assay (PLA) was performed on fixed and permeabilised cells using Duolink In Situ Red kit mouse/rabbit (Sigma-Aldrich, DUO92101), according to the manufacturer’s protocol. Briefly, fixed and permeabilised cells were incubated with a blocking solution for 1 h at 37 °C and then incubated with the following primary antibodies: anti-UPF1 (Cell Signaling Technology, 12040; 1:200) and LIN28A (Cell Signaling Technology, 5930; 1:200) overnight at 4 °C. After incubation, the coverslips were washed twice with 1× buffer A, followed by incubation with PLA probes for 1 h at 37 °C. After washing twice with 1× buffer A for 5 min, the coverslip was incubated with the ligation solution for 30 min at 37 °C. Coverslips were washed twice with 1× buffer A, followed by an amplification step with polymerase for 100 min at 37 °C. Finally, the coverslip was washed twice with 1× buffer B and once with 0.01× buffer B and then mounted in VECTASHIELD with DAPI mounting medium (Vector Laboratories, H1200).

BEAS-2B cells grown on 10mm coverslips were mock infected or infected with HMPV at an M.O.I. of 2, and 24 h.p.i., cells were fixed with 4% PFA and permeabilized with 1% Triton X-100-PBS. Cells were then incubated in blocking solution at 37°C for 2 hours. A mouse primary antibody for HMPV P and a rabbit β-actin antibody or rabbit α tubulin antibody were added and incubated overnight at 4°C. A proximity ligation assay was then performed using Duolink In Situ red mouse/rabbit kit (Sigma, DUO92101). PLA probes diluted 1:5 were added, and cells were incubated for 1 hour at 37°C in a humidified chamber and processed for ligation for an additional 30 minutes at 37°C. Cells were then washed twice, polymerase was added and DNA was amplified with a florescent substrate for 100 min at 37°C. Coverslips were then mounted on glass slides using Vectashield, and images were taken on a Nikon A1 confocal laser microscope. Images were processed and analyzed for total fluorescent intensity using BlobFinder software.

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.
