Fmoc-Ala-Glu-Asn-Lys-NH2 is a peptide inhibitor that selectively targets asparagine endopeptidase (AEP) and inhibits the cleavage of amyloid precursor protein (APP). AEP, a pH-controlled cysteine proteinase, plays a crucial role in the proteolytic processing of APP, and its activity is enhanced during the aging process [1].


| Description | Fmoc-Ala-Glu-Asn-Lys-NH2 is a peptide inhibitor that selectively targets asparagine endopeptidase (AEP) and inhibits the cleavage of amyloid precursor protein (APP). AEP, a pH-controlled cysteine proteinase, plays a crucial role in the proteolytic processing of APP, and its activity is enhanced during the aging process [1]. |
| In vitro | Fmoc-Ala-Glu-Asn-Lys-NH2 antagonizes APP processing by AEP, unlike other small molecule inhibitors and the inactive peptide AEQK, which showed no effect [1]. |

DMSO
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
