Antibody Purification

We offer a variety of methods for antibody purification from serum, ascites, and culture supernatants. We use a variety of methods for the purification of antibodies from serum, ascites, and culture supernatants, including ammonium salt precipitation, ion exchange and size exclusion chromatography, IMAC, GST, protein A, and protein G affinity chromatography, and custom affinity chromatography.

Services We Offer :

Affinity purification permits isolation of antibodies against the immunizing antigen, thereby eliminating cross-reactivity that would be present in unpurified serum. Antibodies of extremely high purity and specificity can be obtained by using custom affinity chromatography.
Protein A, G, and A/G Purification
High yields of pure IgG can be obtained in a single-step purification using Protein A affinity chromatography, which differ in their ability to bind antibodies
