General description

Deposits of amyloid protein in senile plaques near nerve processes are found in the brains of aged humand and cases of Alzheimer′s Disease. The principle component of this extracellular amyloid is beta/A4, a 4 kDa peptide derived from a larger amyloid precursor protein (APP), which is widely expressed in the brain and body. The creation, transport and function of these proteins are currently under investigation Reacts with pre-A4.

Physical form

Liquid diluted in PBS, pH 7.2 with stabilizers, 0.2% Tween 20, and 0.1% Kathon as preservative.

Format: Purified

Specificity

The antibody recognizes amino acids 66-81 of the N-terminus on the pre-A4 molecule (Hilbich et al., 1993). 22C11 recognizes all three isoforms of APP, immature ~110kDa, sAPP ~120kDa, and mature ~130kDa (Hoffmann et al., 2000). The antibody is known to cross react with APLP2 (Slunt, 1994).

Storage and Stability
