Purification of human antibody from transgenic corn using aqueous two-phase systems
Keywords and Phrases
"Human antibodies that are very important for the immune system can be produced in transgenic corn. However, their expression is low, less than 4% purity. The consequence of this low expression is an increase in the down-stream processing. Therefore, it is necessary to develop novel and economical purification processes to fully benefit from plant host systems. A recombinant human antibody expressed in corn was separated from its impurities using aqueous two-phase extraction. PEG/potassium phosphate, PEG/sodium citrate, and PEG/ammonium phosphate aqueous two-phase systems were used. The effect of pH, temperature, molecular weight of PEG, total concentration of the phase-forming species, and low concentration of NaCl were investigated to determine optimum separation conditions"--Abstract, leaf iii.
