title: Enzyme-labeled type III bacterial Fc receptors. A versatile tracer for immunoassay.
abstract: The type III bacterial Fc receptor isolated form a group C streptococcus has been conjugated to alkaline phosphatase and used as a tracer in a variety of direct and indirect immunoassays. These immunoassays have utilized specific antibodies prepared in species whose immunoglobulins are poorly reactive with the type I Fc receptor, staphylococcal protein A. The value of the type III Fc receptor as a tracer for immunoassays utilizing antibodies produced in sheep and goats is documented.
