WebSep 10, 1970 · Aspartyl-proline peptide bonds have been found to be hydrolyzed during exposure to low pH values under conditions where other aspartyl bonds are stable. The mechanism of this hydrolytic reaction is concluded to proceed via intramolecular catalysis by carboxylate anion displacement of the protonated nitrogen of the peptide bond. WebNov 5, 2024 · Briefly, the lipid strips were blocked with blocking buffer (10 mM MES pH 5.5, 25 mM NaCl, 2% BSA, and 0.05% Tween-20) for 1 hour at room temperature. Recombinant purified SPRR2A proteins were diluted to 1 μg/ml in blocking buffer and incubated with the lipid strip overnight at 4°C.
