Protein G Excellose |
|
|
| Description |
Protein G Excellose® is protein G immobilized by the CNBr method to CNBr activated Excellose. Protein G binds to the Fc region of IgG from a variety of mammalian species. Protein G Excellose may be used to isolate and purify classes, subclasses and fragments of immunoglobulins from any biological fluid or cell culture medium. Since only the Fc region is involved in binding, the Fab region is still available for binding antigen. Hence, Protein G Excellose is extremely useful for isolation of immune complexes.
The potential applications of protein G include practically all of the current and projected applications of protein A. Protein G and Protein A, however, have different IgG binding species, dependent on the origin of the IgG. |
