Description The 57-amino acid peptide results from the gama-secretase cleavage of the C-terminus of beta-amyloid precursor protein (APP) at Ala713-Thr714. This is also naturally generated in conjunction with Abeta,1-42. May also serve as one of the precursors for the generation of the toxic C31, fragment of APP (Cat. No. A-1201) in vivo.
