Protein A, Cas 91932-65-9, ELISA or Immunohistochemical Tests
Recombinant Protein A
Source:Protein A mutant of Staphylococcus aureus , expressed in E. Coli.
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.
