ABSTRACT
Objective To construct a new secreting recombinant hIFN-?-2B-BCG to provide a new tool for the treatment of bladder tumor. Methods BCG was genetically engineered to secrete recombinant human interferon-alpha 2B by transforming of shuttle plasmid phIFN-?-2B. Expression of hIFN-? was readily detectable by ELISA. Results The phIFN-?-2B was transformed in BCG correctly,and the value of hIFN-?-2B in supernatant of recombinant BCG culture was calculated to approximately 997.2 pg/ml. Conclusions This study demonstrates that the recombinant phIFN-?-2B can be expressed in BCG secretively. As the construction of the plasmid and its transformation and expression in BCG were accomplished successfully, a foundation of reformed BCG and new vaccine will be established.
