Sirius Red F 3B (Direct Red 80) is an azo dye primarily used in staining methods for collagen and amyloid.[1] It has the molecular formula C45H26N10Na6O21S6.
In histology, sirius red staining is used in various domains of diagnostic to observe fibrosis levels in a lot of cases of inflammation induced by cancer, vascular or metabolic pathologies.[2]
In bright field microscopy the following can be observed:
- The nuclei in yellow
- The cytoplasm in yellow
- Collagen fibers in red
- Muscular fibers in yellow
- Red blood cells in yellow
