What is the preferred micrometer thickness for sections to be stained by the technique shown?

Explanation:
The key idea is that tissue section thickness determines how well stains penetrate and how clearly the tissue architecture is preserved under the microscope. For the technique shown, 10 to 15 micrometers strikes a balance: there’s enough tissue mass to maintain structural detail, but not so much thickness that the dye cannot diffuse evenly through the section. If sections are thinner, around 5–10 μm, they can be fragile and prone to tearing or drying artifacts, and some details may be lost. If they are thicker, 20–25 or 30–40 μm, stain diffusion becomes uneven, leading to patchy or weak staining and reduced optical clarity due to increased light scattering. So, 10–15 μm provides reliable, uniform staining with good morphology for the presented technique.
