Microwave antigen retrieval of beta-amyloid precursor protein immunoreactivity. 1994

Formalin fixation reduces beta-amyloid precursor protein (beta APP) immunoreactivity which restricts its study in archival tissue. Formic acid pretreatment has previously been used in an attempt to overcome this problem, but makes the sections very friable. In the present study, a microwave antigen retrieval method has been compared with formic acid pretreatment for retrieving beta APP immunoreactivity in formalin-fixed, paraffin-embedded human brain tissue. Microwave treatment resulted in superior retrieval of beta APP antigenicity in dystrophic neurites in Alzheimer's disease and in injured axons after head injury, using antibodies to three different epitopes. Unlike formic acid, microwave treatment causes minimal adverse effects on the strength and slide adhesion of the sections.

D005557	Formaldehyde	A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)	Formalin,Formol,Methanal,Oxomethane
D006259	Craniocerebral Trauma	Traumatic injuries involving the cranium and intracranial structures (i.e., BRAIN; CRANIAL NERVES; MENINGES; and other structures). Injuries may be classified by whether or not the skull is penetrated (i.e., penetrating vs. nonpenetrating) or whether there is an associated hemorrhage.

D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.

D016501	Neurites	In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of dendrites or a single axon or they may be reabsorbed at a later stage of development. "Neurite" may refer to any filamentous or pointed outgrowth of an embryonal or tissue-culture neural cell.	Neurite
