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 is currently an active area of research.


Reacts with pre-A4. 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).


Epitope: a.a. 66-81 of APP {N-terminus}
Purified recombinant Alzheimer precursor A4 (pre A4695) fusion protein.



Immunohistochemistry: 5-10 μg/mL on 4% paraformaldehyde/15% picric acid perfused and fixed rat spinal cord. 22C11 also works in paraffin embedded tissues but at lower dilutions (1:10-1:20).

Western blot: reducing conditions, 10μg/ml.

Optimal working dilutions and protocols must be determined by the end user.
