Anti-beta Amyloid Peptide 42 Antibody [NT 4A2]

This Mouse monoclonal IgG1 antibody from Antibodies.com selectively recognizes the 42-amino-acid isoform of beta amyloid peptide (Aβ42), the proteolytic fragment most strongly implicated in senile plaque formation and Alzheimer's disease pathology. Supplied as a lyophilised 100 µg vial, the unconjugated primary antibody is raised in mouse and validated for ELISA workflows against human samples. Clone NT 4A2 targets the C-terminal region unique to Aβ42, allowing discrimination from the shorter Aβ40 species that co-occur in research samples. Reconstitution in buffer prior to use restores full binding activity; the lyophilised format supports stable refrigerated storage with protection from light, and aliquoted working stocks can be frozen for longer-term retention. Researchers investigating amyloidogenic processing, plaque deposition, and neurodegenerative disease models rely on isoform-specific detection of Aβ42 versus Aβ40 to interpret ELISA signals accurately.
