1.MECHANISM OF ACTION

This peptide fragment acts primarily as a specific antigenic target or a molecular probe in experimental settings. Its sequence is recognized by antibodies raised against APP, allowing it to be used in immunoassays like ELISA and Western Blot to detect APP expression or cleavage. In functional studies, it can potentially interfere with or modulate interactions between APP and its processing enzymes (e.g., BACE1, γ-secretase), providing insights into the proteolytic events that lead to the production of neurotoxic amyloid-beta peptides.

2.PRODUCT INDICATIONS

This product is indicated for use in foundational neuroscience and Alzheimer's disease research. Its primary applications include the generation and characterization of polyclonal and monoclonal antibodies specific to the APP protein. It is also employed in epitope mapping studies, as a blocking agent in immunohistochemistry, and as a standard or control in assays designed to investigate APP metabolism, protein-protein interactions, and the molecular pathways contributing to amyloid plaque formation.

3.CLINICAL EFFICACY OF PRODUCT

In a research context, APP₇₇₀ (394-410) demonstrates high efficacy as a well-defined immunological reagent. Studies utilizing this peptide have successfully generated specific antisera with strong reactivity to native APP, enabling sensitive detection and quantification in biological samples. Its use has contributed to elucidating APP's role in disease models, validating its utility as a critical component for advancing diagnostic development and therapeutic target validation in neurodegenerative disease research.
