Cells were fixed with 4% paraformaldehyde in PBS for 20 min at room temperature and washed with PBS. Cells were permeabilized with 0.1% Triton X-100 in PBS at room temperature for 5 min. After blocking with 3% non-fat dry milk for 30 min, cells were incubated with mouse monoclonal anti-influenza A nucleoprotein (AbD Serotec); bound antibodies were revealed with goat anti-mouse IgG conjugated with Alexa Fluor 568 (Molecular Probes). After washing, nuclei were stained with 1 μg ml−1 4′,6-diamidino-2-phenylindole (DAPI; Molecular Probes) in PBS for 15 min at room temperature. Fluorescent images were acquired on an Olympus IX70 microscope equipped with Nanomover and softWoRx DeltaVision image acquisition software (Applied Precision, WA, USA) and a U-PLAN-APO 60× objective. Images were captured under constant exposure time, gain and offset. To improve the contrast and resolution of digital images captured in the microscope, they were elaborated with deconvolution software.

The cultured cells on coverslips were fixed in 4% formaldehyde, permeabilized by incubation in 0.5% Triton X-100, blocked with 10% goat serum, and then stained with polyclonal anti-fibronectin (Sigma-Aldrich) followed by Alexa-647 conjugated goat anti-rabbit antibody (Molecular Probes/Invitrogen). Afterwards, the samples were stained for f-actin, g-actin by Alexa Fluor® 488 phalloidin and the nuclei by DAPI (Molecular Probes/Invitrogen). To assess the presence of platelets in the colonic mucosa, sectioned colonic tissue mounted on the slides were stained with a rat anti-CD41 antibody, followed by a FITC conjugated goat anti-rat polyclonal antibody, and the nuclei by DAPI, based upon a previously described technique (31 (link), 32 (link)).
Finally, samples were mounted on slides with elvanol (DuPont). Specimens were then visualized either by Deconvolution Microscopy employing an Olympus IX-70 microscope connected to a DeltaVision imaging system (Applied Precision, Issaquah WA), or Nikon A1R confocal laser microscope system and the NIS-Elements C software. The quantitation of immunofluorescence density was done using ImageJ software by measuring pixel units.

Immunofluorescence images were taken using an Olympus UPlanS APO 100X objective lens (numerical aperture 1.40) on an Olympus IX-70 microscope equipped with the DeltaVision RT (Applied Precision) imaging system. Z-section image series were collected at 0.2 μM intervals over a total of 3–4 μM through the center of the cells and deconvolved using softWoRx (Applied Precision).

Cells were fixed in methanol : acetone (50 : 50, V/V) for 20 min at -20°C. After blocking with PBS containing 1% bovine serum albumin (BSA) for at least 30 min, cells were incubated with mouse monoclonal antihepatitis C virus core 1b antibody (Abcam, AB 58713); bound antibodies were revealed with mouse anti-human IgG conjugated with Alexa Fluor 488 (Life Technologies, Z25102). After washing, the nuclei were stained with 1 μg/ml 4,6-diamidino-2-phenylindole (DAPI; Molecular Probes) in PBS for 15 min at room temperature. Fluorescent images were acquired on an Olympus IX70 microscope equipped with Nanomover and softWoRx DeltaVision image acquisition software (Applied Precision, WA, USA) and a U-PLAN-APO 40× objective. Images were captured under constant exposure time, gain, and offset.

Images were taken using an Olympus UPlanS APO 100X objective lens (numerical aperture 1.40) on an Olympus IX-70 microscope equipped with the DeltaVision RT (Applied Precision, GE Healthcare) imaging system. Z-section image series were collected at 0.2 μM intervals over a total of 3–4 μM through the center of the cells. All protein and DNA localization was done with images that had been deconvolved using SoftWoRx (Applied Precision, GE Healthcare).
The images were converted into RGB.tif files using the image processing software Fiji. To reduce background, the red, green and blue channel levels were all set to a minimum level of 25 on a scale from 1 to 255 using Photoshop.

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.
