Human Amyloid Beta 42/Abeta 42 Protein (AMB-HE042) Summary
Product Description |
Recombinant Human Amyloid Beta 42/Abeta 42 Protein is expressed from E.coli without tag.It contains Asp672-Ala713. |
Product Background |
Multiple lines of evidence indicate that the amyloid β peptide (Aβ) plays an important role in the pathogenesis of Alzheimer's disease. In nature, Aβ does not occur as a single molecular species, an more than 20 different Aβ sequences have been detected in human cerebrospinal fluid an brain. The most common Aβ isoform is Aβ1–40, a 40-residue peptide that begins at Asp1 an terminates a Val40. Increased production of Aβ1–42, a peptide that differs from Aβ1–40 by addition of Ile and Ala to the C-terminus, is particularly associated with disease. |
