Mucosubstances in the porcine gastrointestinal tract: Fixation, staining and quantification [PDF]
, 2019 Mucins are of great interest in intestinal research and histochemical methods are often employed to identify them. Since it is in the nature of mucins that they are “hard to hold onto” once they come into contact with water, a frequently used medium in ...

Hormone immunolabeling in resin-embedded Arabidopsis tissues
STAR Protocols, 2023 Here, we present a protocol for immunolabeling of molecules in Arabidopsis tissues. We describe steps for tissue fixation and embedding in resin of microtome-derived sections, immunolabeling using fluorescent and non-fluorescent secondary antibodies, and visualization of cytokinin and auxin molecules.

Paraffin-embedding for large volume bio-tissue [PDF]
Scientific Reports, 2020 AbstractAcquiring ultrahigh-resolution three-dimensional images of large-volume tissues non-human primate tissues was an enormous challenge. Given the preservation of structure and excellent sectioning property, formalin-fixed paraffin-embedding method had an enormous potential for three-dimensional reconstruction of fine structures, based on the very ...

Intranuclear birefringent inclusions in paraffin sections by polychromatic polarization microscopy
Scientific Reports, 2021 Intranuclear birefringent inclusions (IBI) found in various cell types in paraffin-embedded tissue sections have long been considered to be a tissue processing artifact, although an association with biological processes has been suggested.
