beta Amyloid

 

Conformation-specific beta-Amyloid antibody for Alzheimer's disease research

Alzheimer’s disease (AD) pathogenesis is widely believed to be driven by the production and deposition of neurotoxic β-Amyloid peptide (Aβ) aggregates that form plaques in the brain. The Aβ molecules are generated from Amyloid Precursor Protein (APP) via β- and γ- secretase cleavage to produce Aβ monomers. Most of the Aβ peptides are 40 amino acids in length (Aβ 1-40, Aβ40), with a small percentage containing 42 residues (Aβ 1-42, Aβ42). These additional two C-terminal amino acids in Aβ42 confer a greater tendency to misfold and subsequently aggregate. Thus, Aβ42 is considered to be more neurotoxic than Aβ40.

 

GeneTex’s “beta-Amyloid (1-42) antibody – Conformation-Specific (GTX134510, Rabbit pAb) and (GTX635160, mouse mAb)” against Aβ 1-42 oligomers can specifically detect amyloid plaques in the AD brain by IHC-P analysis. The superior specificity and sensitivity of GTX134510 and GTX635160 were confirmed by dot blot and side-by-side IHC-P comparison.
