β-Amyloid (25-35), HFIP-treated  (Synonyms: Amyloid beta-peptide (25-35), HFIP-treated; Aβ25-35, HFIP-treated; β-Amyloid peptide (25-35), HFIP-treated)

β-Amyloid (25-35) (Amyloid beta-peptide (25-35)), HFIP-treated is a β-Amyloid (25-35) (HY-P0128) treated with HFIP. β-Amyloid (25-35) (Amyloid beta-peptide (25-35)) is the fragment Aβ(25-35) of the Alzheimer's amyloid β-peptide, has shown neurotoxic activities in cultured cells^[1].

The amino acid sequence of Aβ(25-35) peptide is NH₂-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Met-COOH, where the first Gly represents the amino acid 25 and the last Met represents the amino acid 35. Amyloid beta-peptide(25-35) is also investigated in gel state for the first time. Comparative studies are also carried out using vibrational absorption and ECD. The conformational preference of Aβ(25-35) peptide film is also investigated using vibrational absorption and VCD spectroscopy^[1].
Amyloid beta-peptide(25-35) induces apoptotic effects on isolated brain mitochondria and the redox state of methionine-35, plays a key role in the induction of programmed cellular death pathways and toxic events^[2].
β-Amyloid Aggregation Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. The resulting film is dissolved in anhydrous DMSO at 5 mM and then dilutes into the appropriate concentration and buffer (serum- and phenol red-free culture medium) with vortexing.
2. Next, the solution is age 48 h at 4-8 °C. The sample is then centrifuged at 14000g for 10 min at 4-8 °C; the soluble oligomers are in the supernatant. The supernatant is diluted 10-200-fold for experiments.
Methods vary depends on the downstream applications.
