Product information "Purification Media, Affinity, Protein A Beads"
The origin of Protein A is from the bacteria Staphylococcus aureus. Protein A is capable of binding most classes and subclasses of immunoglobulins from goat, rabbit, mouse and human., Protein A beads are produced using genetically engineered form of Protein A. Nonessential regions have been removed while leaving the immunoglobulins binding sites intact. The recombinant Protein A has been immobilized to agrose beads using TargetLock chemistry, in order to create a more stable product for the affinity purification and immunoprecipitation of various mammalian immunoglobulins. Protein A beads are being routinely used for the isolation of IgG from several species of mammals. The binding of Protein A to IgGs vary between animal species and between IgG subclasses within the same species. Major limitation of protein A lies with the weak binding it presents towards mouse IgG1, a common IgG subclass. Despite that, Protein A possesses useful, properties that make it a popular choice for the isolation of most types of IgGs. Protein A binds IgGs through the Fc region of the molecules leaving the Fab region available for binding the antigen. Protein A Beads are commomnly used for antibodies purification and for the isolation of immune complexes by Immunoprecipitation.
