"WebHydrolysis of the NHS ester competes with the primary amine reaction. The rate of hydrolysis increases with buffer pH and contributes to less-efficient crosslinking in less-concentrated protein solutions. The half-life of hydrolysis for NHS-ester compounds is 4 to 5 h at pH 7.0 and 0°C. This half-life decreases to 10 mins at pH 8.6 and 4°C. " - Ester hydrolysis with acid
