Polyclonal Antibody : Antibody Purification

1. Ammonium sulfate precipitation

It precipitates the immunoglobuin fraction and removes other serum proteins. It is a free service from EZBiolab

2. Protein A affinity purification

Protein A specifically binds to IgG. Antibodies purified by Protein A column is purer than that by ammonium sulfate precipitation method

3. Peptide affinity purification

An antibody purified by its antigen peptide affinity column is highly specific. Our peptide affinity purification service includes peptide synthesis, affinity column preparation and antibody purification from 40 ml of serum of a rabbit.
