The aim of this study was to report on the interactions between Staphylococcal Protein A (SpA) or Streptococcal Protein G (SpG) and sera from four mammalian species: raccoon, skunk, coyote, and mule using two novel techniques. SpA has a molecular weight of 42 kDa. It binds to the Fc fragment of IgG produced by several animal species. The native protein consists of five domains. Of these, four show high structural homology of about 58 aminoacids and they have binding capacity to immunoglobulins.
