It has been proved that A β 1-42 is more toxic and easier to aggregate, thus forming the core of a β precipitate and causing neurotoxicity. In order to promote the research and cure of Alzheimer's disease, it selected 38 amino acid fragments (3-40) of a β 1-42 for further study. In general, a β is produced by the hydrolysis of app by β - and γ - secretory enzymes, and amino β - protein (3-40) is no exception.
Some of the fragments of aminoid β - protein (3-40) are prone to side reactions, such as hydrolysis or racemization, and His-His-Gln in the sequence is prone to racemization. Go Top Peptide Biotech has rich experience in the production of this kind of peptide. It will select the appropriate production process according to the sequence, so as to produce high-quality products.
