Beta-amyloid N-terminally truncated (9-42) peptide. The degree of amino-terminal truncation varies in different neuritic plaque extractions; however, in studies of several Down’s syndrome patients subjected to neuritic plaque extraction, Aßs 1-42, 1-40, 3-42, 4-42, 5-42, 8-42, and 9-42 have been identified.

Aβ 1-42, 42-residue fragment of amyloid precursor protein, has been found to be a major constituent of the senile plaques formed in the brains of patients with Alzheimer's disease and late Down's syndrome. Aβ 1-42 readily forms neurotoxic oligomers at physiological pH. On the other hand, the peptide shows antimicrobial activity. The sequence of H-1368 corresponds to the human, bovine, canine, feline, ovine, guinea pig, and rabbit Aβ42 peptide. The peptide has been used to detect amyloid β-protein multimers in the cerebrospinal fluid of Alzheimer's disease patients through fluorescence correlation spectroscopy. For detailed descriptions of the preparation of Aβ 1-42 monomers and protofibrils please see the papers of Jan, Hartley, and Lashuel, Stine et al. (2011), and of Broersen and colleagues. The findings of Ryan et al. indicate that 10% ammonia disaggregates Aβ42 more efficiently than HFIP.

Beta-Amyloid N-terminally truncated (4-42) is highly abundant in Alzheimer disease (AD) brain and was the first Aβ peptide discovered in AD plaques. Aβ 4-42 rapidly forms aggregates possessing a high aggregation propensity in terms of monomer consumption and oligomer formation.

This peptide is beta-amyloid (1-42) N-terminally truncated. It is the non-pyroglatamate form of beta-Amyloid (3-42). N-terminally truncated pyroglutamate-modified beta-Amyloid forms such as Aß(3-42) and Aß (11- 42) have been described as major compounds in the senile plaques. Pyro-Glu modified beta-Amyloid forms are more resistant to degradation, show higher toxicity and have increased aggregation propensity compared to non-modified beta-Amyloid.

b (1-42), hydrochloride

Supplier: Bachem Americas

(Met(O)³⁵)-Amyloid β-protein (1-42) (H-5888), in contrast to Aβ 1-42 (H-1368), has been shown to be non-toxic to 9-11 day-old rat embryonic hippocampal neuronal cultures and not to produce any protein oxidation. It has also been demonstrated that fibril formation is not affected by Met(O)³⁵. For the Nle analog see H-7308.

This peptide is from amino acid 3-42 of the full length 42-amino acid long GIP (Glucose-dependent Insulinotropic Polypeptide or also known as Gastric Inhibitory Polypeptide). The in-vivo degradation of the first two N-terminal amino acids (Tyr-Ala) by the enzyme dipeptidyl peptidase IV (DPP IV) results in making GIP (3-42) a potent antagonist as opposed to the agonist full length GIP on the GIP receptor.
