Beta-Amyloid (3-42)

UNSPSC code: 12352209

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. | Pyroglutamyl (pGlu) peptides may spontaneously form when either Glutamine (Q) or Glutamic acid (E) is located at the sequence N-terminus. The conversion of Q or E to pGlu is a natural occurrence and in general it is believed that the hydrophobic γ-lactam ring of pGlu may play a role in peptide stability against gastrointestinal proteases. Pyroglutamyl peptides are therefore considered a normal subset of such peptides and are included as part of the peptide purity during HPLC analysis. (Shipping Cost: €35.00)
