Immunofluorescence

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.

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.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Physical form

Protein A purified

Format: Purified

Protein A Purified mouse immunoglobulin in 20 mM sodium phosphate, 250 mM NaCl, pH. 7.6, with 0.1% sodium azide as a preservative.

Specificity

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).

Storage and Stability

Maintain for 1 year at 2–8°C from date of shipment. Aliquot to avoid repeated freezing and thawing. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
