Plastic sections maintain true tissue morphology in thin sections of tissue that can be immunostained with fluorescent secondary antibodies, making this method more useful than paraffin-embedded or frozen sections for many types of tissue. The method for staining, plastic embedding, and sectioning is demonstrated in this video.

FAQs
Orientation determines the anatomical plane displayed in a frozen-section analysis. Positioning the specimen within OCT compound before freezing lets the resulting sections represent the intended tissue architecture. The solidified medium provides physical support as the cryostat cuts thin sections, which can then be placed on slides for microscopy or downstream analysis.
Rapid freezing converts the water-soluble OCT medium into a solid support around the specimen while the sample remains at a low temperature. This combination enables thin cryostat sectioning and helps preserve tissue structure and temperature-sensitive components for later staining, imaging, or molecular analysis.
OCT embedding supports analysis when chemical fixation and paraffin processing could alter features of interest. Its frozen-section approach avoids relying on those processing steps and can retain temperature-sensitive components within the tissue. This makes it useful for examining native architecture, protein localization, cellular distribution, or molecular signals that may otherwise change.
The cryostat produces thin sections from the frozen OCT-supported specimen. Section thickness and continuity allow tissue architecture to be examined on microscope slides, while the preserved sample can undergo histological staining, immunohistochemistry, fluorescence imaging, or molecular analysis. The instrument therefore connects frozen sample preparation with the analytical stages of a biological experiment.
Sections prepared with OCT can support several complementary readouts. Histological staining reveals tissue organization, immunohistochemistry helps localize proteins, and fluorescence imaging can show labeled structures or cells. Molecular analysis adds information beyond morphology. Selecting among these approaches depends on whether the study emphasizes architecture, protein distribution, cellular localization, or molecular features.
This method is particularly valuable when researchers need to preserve tissue structure while examining temperature-sensitive components or localized biological features. It supports studies of tissue architecture, protein or cell distribution, and samples that may be changed by chemical fixation or paraffin processing. The resulting sections provide a practical format for combining morphology with targeted imaging or molecular analysis.
