The Using of Serum Free Media for the Production of J93-463-1-16-10 Monoclonal Antibody against Japanese encephalitis virus

The development of J93-463-1-16-10 cell culture by sequential adaptation method in serum-free media of Hybridoma-SFM medium and CD Hybridoma medium to produce the monoclonal antibody specific to Japanese encephalitis virus was shown that the viabilities of J93-463-1-16-10 were more than 70%. Then the supernatant from the cell culture was purified after precipitation with ammonium sulfate until the final concentration was 50% in order to separate the IgG. After that, the protein concentrations were measured by using the Bradford assay. Next, the proteins were separated, which made each protein purer with SDS-PAGE method in order to find the molecular weights of the separated proteins. The putative IgG and its heavy chains and light chains were divided in two sizes which were approximate 23-25 kDa and 50-53 kDa respectively. Later, the type of immunoglobulin will be identified by the Matrix-assisted Laser Desorption/Ionization Time of Flight (MALDI-TOF) method and its antibody characteristic to Japanese encephalitis virus which will be done further.

In the future, a monoclonal antibody in this research could be used to study the expression of the envelope protein of Japanese encephalitis virus in green cos and red cos, and to develop the vaccine for Japanese encephalitis virus in swine.
