      ApplicationSubstrate Cleavage Assays (30-100 μg/ml)
      DescriptionWild-type, human Aβ1-42 peptide. A number of mutations, identified in the gene encoding the β-amyloid precursor protein (βAPP), have been linked to early-onset Familial Alzheimer’s Disease. Mutations in the genes encoding presenilin 1 and presenilin 2 have also been shown to alter the processing of βAPP, resulting in increased extracellular concentration of β-amyloid peptide Aβ1-42(43) relative to Aβ1-40. Biophysical and biochemical experiments suggest that Aβ1-42(43) may serve as a catalyst for the aggregation and deposition of β-amyloid peptide (Aβ) leading to neurotoxic effects associated with senile plaque formation. Furthermore, antibodies recog-nizing Aβ1-42 revealed that the long form of the peptide is increased in presenilin and βAPP mutants, while other studies have used Aβ specific antibodies to prevent the in vitro fibrillar aggregation of Aβ. Amino acid sequence verified by amino acid analysis or sequencing. This product is supplied in a form that is not neurotoxic prior to a preincubation step. The appearance of toxicity has recently been shown to correlate to the extent of β sheet structure. Useful for neurotoxicity studies and substrate cleavage assays.

      FormLyophilized
      FormulationSupplied as a chloride salt.
      Recommended reaction conditionsDissolve the lyophilized peptide at 1 mg/ml in 50 mM Tris-HCl, pH ≥9.0. Dilute peptide to an appropriate concentration with calcium, magnesium-free PBS and incubate at 37°C for 24-48 h prior to neurotoxicity studies. Suggested neurotoxic concentration is 30-100 µg/ml.
