Abstract
A fused protein for use in an enzyme immunoassay system. The protein comprises an enzymatically active .beta.-galactosidase fused, at its C terminus, to an immunologically active peptide. The protein is produced using a plasmid containing a complete .beta.-galactosidase gene fused, at its 3' end, with an oligonucleotide coding for the peptide. The fused protein is designed for use in a solid-phase enzyme immunoassay system, based on immunospecific binding of the fused protein to a solid support, or in a homogeneous enzyme immunoassay system, based on enzyme inhibition resulting from immunospecific binding of an antibody to the protein.
