5-FAM-Amyloid-B (1-42) Peptide (human) (trifluoroacetate salt)

5-FAM-Amyloid-B (1-42) peptide is a fluorescently labeled amyloid-B peptide. Amyloid-B (1-42) (AB42) peptide (Item No. 20574) is the primary form of AB found in amyloid plaques in postmortem cerebral cortex from patients with Alzheimer's disease and its aggregation results in the formation of neurotoxic fibrils or globular oligomers.{10614,42695} 5-FAM-Amyloid-B (1-42) is a labeled form of AB42 containing 5-carboxyfluorescein (5-FAM; Item No. 19581), which displays excitation/emission maxima of 492/518 nm, respectively.
