Micrograph demonstrating amyloid deposition (red-orange) with Congo red staining in cardiac amyloidosis. In histology and microscopy, Congo red is used for staining in amyloidosis, and for the cell walls of plants and fungi, and for the outer membrane of Gram-negative bacteria.
The most useful stain in the diagnosis of amyloid is Congo red, which, combined with polarized light, makes the amyloid proteins appear apple-green on microscopy. Also, thioflavin T stain may be used. [22] A number of imaging techniques such as a Nuclear Medicine PYP scan, DPD scan or SAP scan are also in use. [23]
Amyloid shows up as homogeneous pink material in lamina propria and around blood vessels. 20× magnification. Amyloids are aggregates of proteins characterised by a fibrillar morphology of typically 7–13 nm in diameter, a β-sheet secondary structure (known as cross-β) and ability to be stained by particular dyes, such as Congo red.

Cerebral amyloid angiopathy; Other names: Congophilic angiopathy [1] Micrograph of cerebral amyloid angiopathy using congo red stain: Specialty: Neurology Causes: Cause of CAA is unknown [2] Diagnostic method: PET scan, CT scan [2] Treatment: Management can be physical, occupational, or speech therapy. [2]
In this histological evaluation special stains are utilized to visualize the amyloid deposits. [7] One such stain is Congo Red, which binds specifically to the amyloid deposit and can be characterized by various lighting methods. [7] Under polarized light, the amyloid deposits while show pathognomonic apple green birefringence, and under plain ...
Amyloid plaques are visible with the light microscope using a variety of staining techniques, including silver stains, Congo red, Thioflavin, cresyl violet, PAS-reaction, and luminescent conjugated oligothiophenes (LCOs).
Example of amyloid deposits under Congo Red staining LECT2 Amyloidosis (ALECT2) is a form of amyloidosis caused by the LECT2 protein. It was found to be the third most common (~3% of total) cause of amyloidosis in a set of more than 4,000 individuals studied at the Mayo Clinic ; the first and second most common forms the disorder were AL ...
Both are used for histology staining and biophysical studies of protein aggregation. [1] In particular, these dyes have been used since 1989 to investigate amyloid formation. [2] They are also used in biophysical studies of the electrophysiology of bacteria. [3] Thioflavins are corrosive, irritant, and acutely toxic, causing serious eye damage. [4]
