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.
