Description: Peptide to [Val671]-APP770 (667-676) Form: Lyophilized powder CAS Number : 252256-43-2Molecular Formula : C51H82N14O18Molecular Weight : 1179.31Purity : > 95%Chemical Structure : Ser-Glu-Val-Lys-Val-Asp-Ala-Glu-Phe-ArgApplication : This peptide substrate corresponds to the M671V mutation of the amyloid precursor protein (APP) β-secretase cleavage site. It has been used for assaying β-secretase activity but no detectable cleavage by the endogenous β-secretase could be observed.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
