In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin amyloideus ("starch-like"). [1]
To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR).

Amyloid light chains deposition in shoulder joint causes enlarged shoulders, also known as "shoulder pad sign". [18] Amyloid light chain depositions can also cause bilateral symmetric polyarthritis. [18] The deposition of amyloid proteins in the bone marrow without causing plasma cell dyscrasias is called amyloidoma. It is commonly found in ...
Amyloid light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form of systemic amyloidosis. [1] The disease is caused when a person's antibody -producing cells do not function properly and produce abnormal protein fibers made of components of antibodies called light chains .
A main theory behind the cause of Alzheimer’s disease is the build-up of the protein amyloid-beta in the brain. Researchers from the University of Cincinnati provide evidence suggesting it’s ...
Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine.Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate.
