1. Also disclosed are expression vectors and systems for producing the polypeptide complexes. 2. CNPV has been used recently as a mammalian expression vector in the vaccine industry. 3. However, it requires use of an expression vector , which can pose safety concerns. 4. What about expression vector plasmids for example? 5. The first generation of expression vectors of this kind used modified " Saccharomyces cerevisiae" 6. Low level of constitutive protein synthesis may occur even in expression vectors with tightly controlled promoters. 7. Hol by itself, when expressed in a broad host-range expression vector under autolysis system. 8. The promoters for cytomegalovirus ( CMV ) and SV40 are commonly used in mammalian expression vectors to drive gene expression. 9. Monobodies belong to the class of molecules collectively called antibody mimics ( or transfecting the cell with a monobody expression vector . 10. An example of the use of expression vector is the production of insulin, which is used for medical treatments of diabetes.
