title: Cloning a synthetic gene for human stefin B and its expression in E. coli.
abstract: A gene coding for human stefin B was synthesized by the solid-phase phosphite method and cloned in the pUC8 cloning vector. The insert with the verified DNA sequence was subcloned into two expression vectors and expressed in E. coli as a fusion protein with beta-galactosidase and as a native protein. The CNBr cleaved fusion protein and the native recombinant stefin B were inhibitory to papain and reacted with antibodies against human stefin B.
