Free DNA Vaccine Plasmids  
These plasmids express the Hepatitis B Surface Antigen (HBsAg) under the control of the CMV promoter and are designed to validate DNA vaccine methods. DNA Vaccine Plasmids are available free-of-charge.

pRc/CMV-HBs(S)
One of the most widely used plasmids in DNA vaccine research.
One of the most widely used plasmids in DNA vaccine research, pRc/CMV-HBs(S) (or simply pCMV-S) expresses the hepatitis B surface antigen (small, or S, protein) under the control of the CMV immediate-early promoter. This plasmid is freely available upon request for validating DNA-based immunization methods and other experimental uses. Antibodies generated to the hepatitis B surface antigen can be measured using ELISA and the results can subsequently be compared to published data.

pCMV-S has been widely used in Gene Therapy and DNA vaccine studies. These include:
  • novel DNA vaccine delivery route studies.
  • liposome, formulation, and stability studies.
  • adjuvant studies.

Please contact us for a current list of pCMV-S references. These will enable you to compare your data to published results.

Please see the following pCMV-S reference for details of its construction and use:
