Descripción general

Pro-Ac (proline acetate) buffer is mainly used as an optimized stabilizing buffer system in biopharmaceuticals, especially for the reconstitution of antibody-drug conjugates (ADCs) and the storage of antibodies. Its standard formulation is typically 100 mM Pro-Ac, 20 mM Arg, pH 5.0.In ADC reconstitution, this buffer protects the chemical stability of linkers (such as cleavable linkers) by maintaining an acidic environment at pH 5.0, slowing down hydrolysis. Through the synergistic effects of proline and arginine (e.g., enhancing hydration and inhibiting protein-protein interactions), it reduces antibody aggregation, controls solution viscosity, and preserves antibody conformation. In antibody storage, Pro-Ac buffer effectively improves the colloidal stability and long-term storage stability of antibodies. The proline contained in it also acts as a natural cryoprotectant, protecting protein structures during freeze-thaw cycles. Compared with traditional buffers (such as acetate or histidine buffers), Pro-Ac provides superior stabilization for ADCs and antibodies around pH 5.0.
