High-Resolution Three-Dimensional Confocal Imaging of the Blood-Brain Barrier in a Mouse Brain Section

Begin with a confocal microscope software and set the image acquisition parameters.

Then, take a mouse brain section mounted on a glass slide. This section is stained with antibodies targeting blood-brain barrier components.

The blood-brain barrier is a selective cellular interface between the bloodstream and the brain to maintain homeostasis.

Apply a drop of immersion oil with a desired refractive index onto the coverslip to optimize resolution and minimize light refraction.

Place the slide on the microscope stage and use the epifluorescence lamp to visualize the sample.

Using the appropriate filters, locate the DAPI-stained nuclei and identify the capillary segment for imaging.

Start the live scanning and adjust the parameters for each fluorescent channel to capture high-quality images.

Finally, define the start and end points for Z-stack acquisition to generate a three-dimensional image of the blood-brain barrier.

In the software's Acquisition menu that controls the microscope, set the image acquisition parameters. In the dropdown menu of image size, select a value of 1,024 by 1,024 pixels. Modify the pixel size to a value between 200 and 300 nanometers by adjusting the value of the Zo
