Molecular cloning, expression and peroxidase conjugation of staphylococcus aureus protein A

ABSTRACT

Background: Staphylococcal protein A [SPA] is a cell wall component of Staphylococcus aureus that binds to different IgG subclasses of human and several animal species. This bacterial protein can be used as an antibody detector in various immunological assays or as an isolation reagent for the purification of antibody molecules via immuno-chromatography procedures
