CAS: 91932-65-9 Cat. No.: R141086 EC Number: 295-242-9 PubChem CID: 363902062

GRADE & PURITY ≥95%, Mw 25kD

Overview

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 monoclonaland 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.
