Recombinant Protein A, Lyophilized Powder, No Antibody Contaminant
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.
Recombinant Protein A is useful as the basis for preparing various
kinds of probes or affinity media
for detection or purification of rabbit and human antibodies,
especially IgG isotypes, in immunoassays
and antibody purification protocols.
