APPLICATION:
Recombinant Protein A
The recombinant Protein A is a genetically engineering protein containing IgG-binding domains.
Recombinant Protein A is ideal for purification of polyclonal or monoclonal IgG antibodies. Protein A binds
to most human and mouse IgG subclasses (e.g., human IgG1, IgG2, IgG4; mouse IgG2, IgG2a, IgG2b,
IgG3). It also binds to cow, guinea pig, hamster, house, pig and rabbit total IgG form.
Recombinant protein A can be coupled to solid separation medium (such as agarose) for monoclonal and
polyclonal antibody purification. Recombinant protein A can be coupled to a variety of molecules (such as
fluorescent molecules, enzyme markers, biotin, colloidal gold and radioactive markers). These coupled
derivatives can be used in antibody test in the process of Western-blot, ELISA or immunohistochemical
tests.
