Abstract

We have developed a rapid method of purifying monoclonal antibody with functional magnetite particles. Protein A, which has an affinity to IgG-type antibody, was immobilized on magnetite particles. The affinity constant of protein A-magnetite to mouse IgG was 9×l06 l/mol. Using such particles, purified antibody of 73% purity was obtained with 60% recovery from mouse hybridoma culture broth. These affinity particles could be regenerated and reused. Using magnetite particles for affinity purification, total operation time was shortened to about 20 min.
