Anti-Amyloid A4, Variant 40, CT (Amyloid beta)

Alzheimers disease (AD) is characterized by the presence of senile plaques in the brain and blood vessel walls. Amyloid Beta A4 (Ab4) protein has been found to be the principal constituent of senile plaques of ADs patients. The amyloid beta-protein precursor (APP) is proteolytically cleaved to generate the 4kD Ab4 protein. Two variants of Ab4 can be detected, Ab-40 short-tailed and Ab-42 long-tailed.
