1.MECHANISM OF ACTION

The acetylation at the N-terminus increases the peptide's resistance to exopeptidase degradation, prolonging its half-life in biological assays. As a truncated and modified core epitope derived from the immunodominant region of MBP, it retains the capacity to be presented by Major Histocompatibility Complex (MHC) Class II molecules. This presentation engages with T-cell receptors (TCRs) with altered avidity and kinetics compared to the native sequence, allowing researchers to probe the subtleties of antigen processing, TCR recognition, and immune synapse formation in autoimmune models.

2.PRODUCT INDICATIONS

This product is indicated for sophisticated research in immunology and neurobiology. Its primary uses include: studying the impact of N-terminal acetylation on antigenicity and immunogenicity, serving as a stabilized antigen in T-cell stimulation and proliferation assays, investigating altered peptide ligand (APL) strategies for immune modulation, and acting as a precise tool for epitope mapping and TCR specificity studies related to experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS).

3.CLINICAL EFFICACY OF PRODUCT

Ac-MBP (4-14) Peptide is a research tool and not a direct clinical therapeutic. Its efficacy is demonstrated in the research setting, where its enhanced stability provides more consistent and reproducible results in vitro and in vivo. Studies utilizing such stabilized analogs contribute to the foundational understanding of antigen-TCR interactions, aiding in the rational design of next-generation antigen-specific therapies and diagnostic tools for autoimmune demyelinating diseases.
