Substrates are essential in histology for several reasons:
Sample Stability: Substrates provide a stable platform for tissue sections, preventing them from moving or folding during staining and observation. Reagent Distribution: They ensure even distribution of staining reagents, leading to more consistent and interpretable results. Cell Adhesion: Certain substrates are designed to enhance the adhesion of cells, which is crucial for accurate analysis and imaging. Optical Clarity: Transparent substrates like glass slides enhance the clarity of microscopic images, allowing for better visualization of cellular structures.
