Label-fracture of cell surfaces by replica staining. [PDF]
Journal of Histochemistry & Cytochemistry, 1988 We introduce replica-staining label-fracture, a method for the cytochemical mapping of membrane surfaces. This method is a corollary of the rationale of label-fracture (Pinto da Silva and Kan, 1984: J Cell Biol 99:1156). After freeze-fracture the exoplasmic halves of the membrane remain attached to the replica.

Digital staining facilitates biomedical microscopy [PDF]
Frontiers in Bioinformatics, 2023 Traditional staining of biological specimens for microscopic imaging entails time-consuming, laborious, and costly procedures, in addition to producing inconsistent labeling and causing irreversible sample damage. In recent years, computational “virtual”

Deep-learning based breast cancer detection for cross-staining histopathology images
Heliyon, 2023 Hematoxylin and eosin (H&E) staining is the gold standard for tissue characterization in routine pathological diagnoses. However, these visible light dyes do not exclusively label the nuclei and cytoplasm, making clear-cut segmentation of staining ...
