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. Applications: Suitable for use in ELISA, Western Blot, and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Western Blot: 1:100-1:1000 Immunohistochemistry (FFPE): 1:100-1:2000. Pretreat sections with 70% formic acid for 10-30 minutes. Antibody should be incubated with sections overnight at 4C. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
