Trifluoroacetic Acid 45-65 amyloid beta precursor protein Homo sapiens 8-9 10090532-3 1999 The assay is based on the extraction of amyloid beta (A beta) from milligram amounts of brain tissue by using 20% acetonitrile in 0.1% trifluoroacetic acid and its detection by Western blotting. Trifluoroacetic Acid 135-155 amyloid beta precursor protein Homo sapiens 40-52 10090532-3 1999 The assay is based on the extraction of amyloid beta (A beta) from milligram amounts of brain tissue by using 20% acetonitrile in 0.1% trifluoroacetic acid and its detection by Western blotting. Trifluoroacetic Acid 135-155 amyloid beta precursor protein Homo sapiens 54-60 33073142-1 2020 The instability of an amide bond with dilute trifluoroacetic acid (TFA) is a rare chemical event. Trifluoroacetic Acid 67-70 amyloid beta precursor protein Homo sapiens 8-9 33073142-3 2020 In the repertoire of unnatural peptidomics, alpha-/beta-hydrazino acids and their peptides are explored for the synthesis of N-amino peptide derivatives, and their amide bonds are stable in TFA (~100%) as natural amide bonds. Trifluoroacetic Acid 190-193 amyloid beta precursor protein Homo sapiens 44-55 33073142-6 2020 Surprisingly, the amide bond of beta-troponylhydrazino peptides is cleavable with TFA (~20%) through the formation of a new heterocyclic molecule N-troponylpyrazolidinone or troponylpyrazolidinone. Trifluoroacetic Acid 82-85 amyloid beta precursor protein Homo sapiens 18-19
