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 Dilution:
ELISA: 1:500-1:50,000
Western Blot: 1:100-1:1,000
Immunohistochemistry (paraffin): 1:100-1:250
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
