SCP0002 Acetyl-Amyloid β 25-35 ≥97% (HPLC)  
A6933 Acetyl-Amyloid β-Protein Fragment 15-20 Amide ≥97% (HPLC), powder Amyloid plaques characteristic of the Alzheimer brain contain fibrils composed of amyloid beta aggregates. Short peptides containing the sequence KLVFF have been shown to bind specifically to the homologous region in Aβ and are used to prevent full length amyloid fibril formation.
SCP0041 [Ala28]-Amyloid β 25-35 ≥95% (HPLC)  
SCP0052 [Glu11]-Amyloid β 1-16 ≥97% (HPLC)  
SCP0042 [Gly35]-Amyloid β 25-35 ≥95% (HPLC)  
SCP0048 Amyloid β 42-1 reverse human ≥95% (HPLC)  
SCP0029 [Gly22]-Amyloid β 1-40 Arctic human ≥95% (HPLC)  
SCP0030 [Gly22]-Amyloid β 1-42 Arctic human ≥98% (HPLC)

A1097 [Asn(4-aminobutyl)1,7,23,Gln(4-aminobutyl)3,11,22]-Amyloid β-Protein 1-40 ≥90% (HPLC) Modified amyloid beta-peptide that may be used to detect plaques in vitro or in vivo allowing for the early diagnosis of Alzheimer′s disease.
A0189 Amyloid β Protein Fragment 1-38 ≥95% (HPLC), powder β-Amyloid peptide that forms cross-β-sheet fibrils of 70-90 Å diameter with similar antigenicity as those found in Alzheimer′s disease.
A1075 Amyloid β Protein Fragment 1-40 ≥90% (HPLC), powder Amyloid β-protein is neurotrophic and neurotoxic in vivo and in vitro in human and rat neuronal cell cultures. β-Amyloid peptides (amino acids 1-42 and 1-43) are the major constituents of senile plaques and neurofibrillary tangles that occur in the hippocampus, neocortex, and amygdala of patients with Alzheimer′s disease.
A9810 Amyloid β Protein Fragment 1-42 The predominant fragment of amyloid β-protein found in the brains of patients with Alzheimer′s disease and Down′s syndrome.
A7712 Amyloid β-Protein Fragment 1-43 Primary constituent of senile plaques and cerebrovascular deposits in Alzheimer′s disease and Down′s syndrome
A4723 Amyloid β-Protein Fragment 17-28 ≥90% (HPLC), lyophilized powder  
A4848 Amyloid β-Protein Fragment 17-40 ≥87% (HPLC), lyophilized powder  
A5080 Amyloid β-Protein Fragment 22-35 ≥95% (HPLC) Has cytotoxic effect on cultured neurons from rat hippocampus in serum free medium. Also forms aggregates and fibrils similar to those of β-amyloid protein in senile plaque cores.
A4559 Amyloid β-Protein Fragment 25-35 ≥97% (HPLC) Functional domain of Aβ required for both neurotrophic and neurotoxic effects.
A2326 Amyloid β-Protein Fragment 40-1 ≥90% (HPLC) Inactive control against Αβ [1-40].
A2201 Amyloid β-Protein Fragment 35-25 ≥95% (HPLC) Inactive control
A5973 Amyloid-β-Protein Fragment 1-40, All D-Amino Acids >70% (HPLC), lyophilized powder This D-amino acid peptide functions as a control useful in elucidating structural dependence of aggregation properties characteristic of the amyloid-β 1-40 peptide associated with plaque formation and Alzheimer′s disease.
A4473 Amyloid β-Protein Fragment 1-40 amide trifluoroacetate salt ≥95% (HPLC), lyophilized powder  
SCP0033 Amyloid β 1-16 rat ≥97% (HPLC)
