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:
