Description
Protein G SepFast HighRes has a particle size of 20 – 50 µm, good for small column run at shorter residence time (i.e. higher flowrate).
Protein G SepFast is a family of affinity chromatography media for the purification of immunoglobulins and binds to the Fc region of IgG from a variety of mammalian species. Protein G SepFast may be used to isolate and purify classes, subclasses and fragments of immunoglobins from any biological fluid or cell culture medium. Protein G SepFast 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 specificities, dependent on the origin of the IgG. Compared to protein A, protein G binds more strongly to polyclonal IgG, for example, from cow, sheep and horse. Furthermore, unlike protein A, protein G binds polyclonal rat IgG, human IgG3 and mouse IgG1.
Protein G SepFast HighRes is developed and supported for production scale chromatography. We offer both loose medium and pre-packed ready-to-use disposable columns.
