Abstract excerpt

A DNA fragment, coding for hepatitis core antigen (HBcAg), was amplified by polymerase chain reaction and inserted into a lambda PL promoter-derived expression vector. The recombinant plasmid was transformed into Escherichia coli and proteins produced after heat induction were analyzed. In addition to the 21 kDa HBcAg protein, several smaller related polypeptides, particularly one of 17 kDa in size, were also...
