Biotin-β-Amyloid (1-42), human TFA  (Synonyms: Biotin-amyloid β-peptide (1-42) (human) TFA)

Biotin-β-Amyloid (1-42), human TFA (Biotin-Amyloid β-Peptide (1-42) (human) TFA) is the botin labeled β-Amyloid (1-42), human TFA (HY-P1363). β-Amyloid (1-42), human TFA is a 42-amino acid peptide which plays a key role in the pathogenesis of Alzheimer disease^[1].

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. Solid Aβ peptide is dissolved in cold hexafluoro-2-propanol (HFIP). The peptide is incubated at room temperature for at least 1 h to establish monomerization and randomization of structure.
2. The HFIP is removed by evaporation, and the resulting peptide is stored as a film at -20 or -80 °C.
3. 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.
4. 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.
