rProtein A Sepharose Buffer Kit (Cat. No. CA000 ) Introduction:
|  | ||||||||||||||||||||||||
rProtein A Sepharose is an affinity medium, designed for the purification of monoclonal and polyclonal antibodies at both laboratory and process scale. The specificity of protein A is primarily for the Fc region of IgG, through which it binds, leaving the antigen binding sites free. However, it can also bind the Fab region through secondary sites. There are differences between the binding affinities for Fc and Fab, usually Fc binding is stronger. The recombinant protein A used in the manufacture of rProtein A Sepharose has been specially engineered to give very high binding capacities. It is produced in E. coli and purified by a multi step chromatographic procedure. Purification does not involve the use of IgG or any other proteins. Contents of the kit:
