Polyclonal antibodies generated from immunizing rabbits or goats can be purified from the immunized animal sera with protein A or protein G affinity resin. As a result, total IgG antibodies in the animal sera are separated and purified from the rest of protein components in the sera. Because of the intensive immunization scheme and usage of highly-effective adjuvant, the immunized animal usually generates a very large amount of antibodies specific to the immunogen, resulting up to 30% of the total IgG antibodies specifically for the antigen. Hence, protein A purified total IgG antibody can be good enough for some research application, and it becomes an effective and cheap alternative to produce polyclonal antibody.
Sino Biological has produced and purified thousands of rabbit and goat polyclonal antibodies. Our experience and high-throughput polyclonal antibody purification capacity is ideal to serve your polyclonal antibody production and purification needs.
