Monoclonal antibodies against herpes simplex viruses
Developments in Biological Standardization
|January 1, 1984
Summary
Researchers developed hybridoma cell lines producing monoclonal antibodies against Herpes Simplex Virus types 1 and 2 (HSV-1 and HSV-2). These antibodies are effective for identifying and typing HSV isolates using indirect immunofluorescence (IIF).
Area of Science:
- Immunology
- Virology
- Biotechnology
Background:
- Herpes Simplex Virus (HSV) infections require accurate typing for diagnosis and treatment.
- Monoclonal antibodies offer specific tools for viral identification.
Purpose of the Study:
- To produce and characterize hybridoma cell lines secreting monoclonal antibodies against HSV-1 and HSV-2.
- To evaluate the utility of these monoclonal antibodies for HSV identification and typing.
Main Methods:
- Production of hybridoma cell lines via immunization of BALB/c mice and cell fusion.
- Screening of hybrid cells using ELISA and indirect immunofluorescence (IIF).
- Characterization of antibody specificity through IIF, plaque reduction tests, and immunoprecipitation.
Main Results:
- Successfully produced hybridoma cell lines secreting monoclonal antibodies against HSV-1 and HSV-2.
- Indirect immunofluorescence (IIF) demonstrated higher specificity than ELISA.
- Approximately half of the antibodies precipitated viral proteins, notably glycoproteins gC and gD.
- Identified 19 hybridomas, with preliminary results showing 3 HSV-1 specific, 1 HSV-2 specific, and 4 group-specific antibodies.
Conclusions:
- Monoclonal antibodies derived from hybridoma cell lines are valuable tools for HSV identification and typing.
- Indirect immunofluorescence (IIF) is a rapid, sensitive, and economical method for HSV typing using these antibodies.
