5-FAM-Amyloid-B (1-28) Peptide (human) (trifluoroacetate salt)

5-FAM-Amyloid-B (1-28) peptide is a fluorescently labeled peptide. Amyloid-B (1-28) (AB28) is a synthetic peptide that lacks 14 C-terminal amino acids and is more soluble than AB42.{47211} AB28 forms fibrils and plaques in vitro that are similar to those formed by AB42 and induces learning deficits in a passive avoidance task in rats.{47212,47213,47214} 5-FAM-Amyloid-B (1-28) is a labeled form of AB28 containing 5-carboxyfluorescein (5-FAM; Item No. 19581), which displays excitation/emission maxima of 492/518 nm, respectively.
