Nucleation is a stochastic phenomenon and the probability of observing the critical nuclei formation is very low. Our aim is to enhance nucleation in the metastable zone enabling us to locate and control it. The first step is to determine the nucleat

Crystal Growth & Design, 2004, 4 (6), pp.1137-1141. ⟨10.1021/cg0498195⟩
In this contribution, we present the phase transition of protein crystals in suspension as a function of temperature and pH. We measure the solubility of two polymorphs of aprotinin (BPTI) in 2 M NaBr solutions at different acidic pH values between 4
