CAT No: R1236
Beta-Amyloid(1-14), mouse, rat is a synthetic peptide fragment corresponding to the N-terminal residues 1 through 14 of the beta-amyloid (Aβ) sequence, derived specifically from murine and rat species. As a truncated segment of the amyloid precursor protein (APP), this peptide is of significant interest in neurodegenerative research, particularly in the context of Alzheimer's disease and amyloidogenesis. Its defined sequence and species specificity make it a valuable tool for studies focusing on the molecular mechanisms of amyloid aggregation, peptide-protein interactions, and the cellular pathways influenced by amyloidogenic fragments. Researchers utilize this peptide to dissect the initial events of amyloid formation and to compare species-specific differences in amyloid processing and recognition.
Aggregation studies: Beta-Amyloid(1-14), mouse, rat serves as a model substrate in investigations of amyloid aggregation and nucleation. By focusing on the N-terminal region, researchers can explore how this segment contributes to the early stages of fibril formation or inhibits aggregation, providing insight into the sequence determinants that modulate amyloidogenic propensity. Such studies are critical for understanding the molecular underpinnings of amyloid plaque development and for identifying potential modulators of aggregation in preclinical models.
Antibody characterization: The defined epitope presented by this peptide makes it an essential tool for the development and validation of antibodies targeting the N-terminal region of amyloid beta. By using Beta-Amyloid(1-14), mouse, rat in immunoassays, researchers can assess antibody specificity, cross-reactivity, and binding affinity, which is pivotal for generating reliable reagents for immunohistochemistry, ELISA, and western blotting applications. These assays support the detection and quantification of amyloid species in biological samples and experimental systems.
Enzyme substrate studies: The peptide's sequence enables its use as a substrate for proteolytic enzymes involved in amyloid precursor protein processing, such as beta- and gamma-secretases. By employing it in enzymatic assays, investigators can monitor cleavage patterns, determine enzyme kinetics, and elucidate the specificity of proteases that act on amyloidogenic sequences. These studies help clarify the biochemical pathways that regulate amyloid production and turnover in murine and rat models.
Cell signaling and toxicity assays: Researchers utilize Beta-Amyloid(1-14), mouse, rat to probe the cellular responses triggered by amyloidogenic fragments. In vitro studies involving neuronal and glial cultures can reveal how exposure to this peptide influences cell signaling pathways, oxidative stress responses, or cytotoxicity. Such applications are instrumental in delineating the role of specific amyloid segments in neurotoxicity and neuroinflammation, enhancing the understanding of disease-relevant cellular mechanisms.
Comparative species analysis: The availability of a mouse and rat-specific beta-amyloid (1-14) sequence allows for comparative studies between rodent and human amyloid peptides. By examining differences in sequence recognition, aggregation behavior, and biological activity, researchers can better interpret the translational relevance of animal models in amyloid research. This comparative approach informs the design of preclinical studies and aids in the evaluation of species-dependent factors that may influence therapeutic development and biomarker discovery.
