15x103 cells were seeded on chamber slides and cultured for 48 hours. Cells were fixed with 4% (w/v) paraformaldehyde in PBS at room temperature for 15 minutes and permeabilized with 0.1% (v/v) Triton-X100 (Sigma-Aldrich, Milan, Italy) for 10 minutes at room temperature. Non-specific binding sites were blocked by incubation in 1% (w/v) bovine serum albumin (BSA) in PBS for 30 minutes at room temperature. Cells were incubated with mouse monoclonal anti-active-βCatenin (1:400, Cell Signaling Technology, Boston, MA, USA) overnight at 4°C and subsequently with FITC-anti-mouse IgG antibody (1:1000, Sigma-Aldrich, Milan, Italy) for 1 hour at room temperature. Nuclei were counterstained with 4',6-diamidino-2-phenylindole (DAPI) using VECTASHIELD® Mounting Medium (Biorad, Hercules, CA, USA) and viewed under a confocal microscope Nikon Eclipse Ti-E microscope equipped with a unique Perfect Focus System (PFS) and coupled to Laser scanning confocal microscope C2 (Nikon Instruments S.p.A, Florence, Italy).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Coverslip-adherent cardiac myocytes were treated with pre-warmed H2O2 (0–1mM) in M199 media for 1 h at 37°C, washed in pre-warmed PBS, and fixed by incubating in 1% paraformaldehyde in pre-warmed PBS for 1h. Coverslips were blocked in blocking buffer containing 3% BSA and 0.1% Triton X-100 in PBS for 30min at room temperature. For immunostaining of α-tubulin, coverslips were probed with mouse anti-α-tubulin antibody (DM1A, VWR; #PI62204; 1:1000 in blocking buffer) for 1h at room temperature, washed twice in blocking buffer for 10min each, and treated with FITC anti-mouse IgG antibody (F0257, Sigma; 1:1000 in blocking buffer) overnight at 4°C. Coverslips were again washed twice in blocking buffer for 10 min and mounted on slides with ProLong Diamond Antifade (Thermo Fisher #P36965) for imaging. Immunostained cardiac myocytes were imaged with a laser scanning confocal microscopy (Nikon Ti2, 488nm laser line) fitted with a 100x oil objective (Nikon N2 Apochromat TIRF 100X Oil, 1.49 NA), which allowed for a 0.2 μm pixel size. The microtubule density was estimated using a custom Matlab code to first detect microtubule area, and then detect the entire cell area. The microtubule area was divided by the total cell area to compute a microtubule density. For each cell, a single slice was selected for analysis just below the nucleus.

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.
