Anti-Amyloid beta Peptide 42 Antibody [CA9 3B3]

This mouse monoclonal IgG2b antibody from Antibodies.com targets Amyloid beta Peptide 42 (Aβ42), the 42-residue isoform that aggregates into senile plaques in Alzheimer's disease brain tissue. The CA9 3B3 clone was raised against the peptide, and the reagent is supplied as 100 µg of lyophilised powder in a single vial for reconstitution at a working concentration matched to the assay of choice.

The unconjugated format supports ELISA and Western blot workflows, with reactivity demonstrated against human, mouse, and rat amyloid-beta sequences. Researchers studying amyloidogenesis and plaque pathology can apply the antibody to immunohistochemistry of brain sections, immunoblotting of cell and tissue lysates, and quantitative immunoassays measuring Aβ42 levels in biological samples.

Aliquot reconstituted stock to limit freeze-thaw cycles and store the lyophilised powder protected from light. The reagent is a useful tool for distinguishing Aβ42 from the shorter Aβ40 species in studies of neurodegenerative disease models and therapeutic candidate screening.
