Assay Report Card

ID: ALA3705765

Type: Binding

Description: Inhitbition Assay: 48.5 .mu.L of substrate peptide solution (Biotin-XSEVNLDAEFRHDSGC-Eu: X=.epsilon.-amino-n-capronic acid, Eu=Europium cryptate) was added to each well of 96-hole half-area plate (a black plate: Costar), and after addition of 0.5 .mu.l of the test compound (dissolved in N,N'-dimethyl formaldehyde) and 1 .mu.l of Recombinant human BACE1(R&D Systems), the reaction mixture was incubated at 30.degree. C. for 3 hours. The substrate peptide was synthesized by reacting Cryptate TBPCOOH mono SMP (CIS bio international) with Biotin-XSEVNLDAEFRHDSGC (Peptide Institute, Inc.). The final concentrations of the substrate peptide and Recombinant human BACE1 were adjusted to 18 nmol/L and 7.4 nmol/L, respectively, and the reaction was performed in sodium acetate buffer (50 mmol/L sodium acetate, pH 5.0, 0.008% Triton X-100).After the incubation for reaction, 50 .mu.l of 8.0 .mu.g/ml Streptavidin-XL665 (CIS bio international) dissolved in phosphate buffer.

Organism: Homo sapiens
