Abstract
Recombinant proteins and peptides are anticipated to become promising tools as reagents for immunoassays because of their constant availability and structural uniformity. However, careful assessment of their immunological properties is necessary prior to practical use. Epitope analysis of recombinant human thyrotropin (rec-hTSH) was recently performed in our laboratory. Details are to be published elsewhere (T. Kashiwai, K. Miyai et al.) but the results are briefly shown here.
