- 5 domain, wide range specificity
- High activity and purity
- Recombinant produced
- Animal free production
- Sterile filtered Lyophilized powder
Protein A orginates from Staphylococcus aureus and has five
antibody binding domains and a cell binding domain. It binds IgG from
most mammalian species and some IgA and IgM through the Fc region.
Medicagos recombinant protein A, "PAII" is produces in E.
coli using animal free media. The recombainat form has the cellbinding
domain removed, for reduced nonspecified binding and leakage.
PAII is supplied as a lyophilized white flocculate. The purity of PAII is
determined by SDS- PAGE, which generates one single band at 42 kDa. The
activity is tested by interaction with human igG. The product is to be
used for laboratory work only.
- Purification of polyclonal and monoclonal antibodies
Directions for use
