          Beta Amyloid peptide 1 to 40, 1-42

              A beta protein (beta amyoid peptide) is 1984 Glenne found neuritis plaques in the brain, such as main ingredients, it is A     composed of 39 ~ 43 of amino acids, with beta folding conformation of proteins, so called beta amyloid protein.

              Beta Amyloid peptide 1-42 (Amyloid beta 1 to 42, hereinafter referred to as A beta 42) is the main component of senile plaques have nerve toxicity, it is Alzheimer's disease (Alzheimer 'sDisease, AD) of the main causes.

              A beta 1 to 42 C the 10 amino acid residues 33-42 and 17-21 five amino acid residues with high hydrophobicity, constituted A beta 1-42 scanty water; 28-42 amino acid residues formed beta folding conformation probability, and 9-21 amino acid residues may also form A beta folding conformation, and beta folding conformation is conducive to A beta 1-42 deposit and plaques.

              As A beta 1-42 protein in alzheimer disease (AD) and to play an important role in the immune therapy, thus further clarify A beta 1 to 42 protein in AD pathogenesis in detail and its role in the immune therapy is of great significance to solve the AD. 

              Kang Long for you to supply a series of beta amyoid peptides, common types are equipped with inventory, quality assurance!
