Application: Tau Peptide (275–305) is a 31-amino-acid fragment derived from the Repeat 2 domain of the human tau protein. Tau repeat domains are essential for microtubule binding and play central roles in tau aggregation, fibril formation, and neurodegenerative disease pathology. This peptide is commonly used to investigate tau aggregation kinetics, structural transitions, repeat-domain function, and isoform-specific mechanisms. Tau Peptide (275–305) serves as a useful model for studying Alzheimer’s disease and related tauopathies. It also supports evaluation of aggregation inhibitors, diagnostic tools, and therapeutic strategies targeting tau pathology.
