Horseradish peroxidase is a key enzyme in bio- and immunochemical analysis. New approaches in functional expression of the peroxidase gene in E. coli cells and the subsequent refolding of the resulting protein yield a recombinant enzyme that is comparable in its spectral and catalytic characteristics to the native plant peroxidase. Genetic engineering approaches allow production of recombinant peroxidase conjugates with both protein antigens and Fab antibody fragments. The present article reviews the use of recombinant horseradish peroxidase as the marker enzyme in ELISA procedures as well as in amperometric sensors based on direct electron transfer.
