Abstract (en)
[origin: WO9006764A1] A method to solubilize immunoglobulins to practical concentrations in aqueous media employs solubilizing preparations of basic amino acids and/or their salts. For example, histidine, lysine, and arginine and mixtures thereof, in effective concentrations are capable of enhancing the solubility of relatively insoluble proteins and immunoglobulins in general, and in particular, of IgG, especially IgG3, and of T4.
