Histological staining

Histological staining is a technique used in microscopy to enhance the contrast of tissue samples. Since tissues are mostly transparent, stains bind selectively to different cellular components, highlighting structures such as nuclei, cytoplasm, or connective tissue. This process helps pathologists and researchers examine tissues in detail, identify abnormalities, and understand tissue organization. Different stains target specific cell parts, making cells and tissue architecture more visible under a microscope for diagnostic and research purposes.
