Hybridoma cell lines secreting monoclonal antibodies against foot-and-mouth disease virus. 1. Cell culturing requirements.
The production of hybridoma cell lines secreting antibody against foot-and-mouth disease virus (FMDV) was more difficult than the production of similar cell lines secreting antibody against vesicular stomatitis virus or measles virus. A rapid and efficient protocol for the selection and culturing of 'anti-FMDV' hybridoma cultures was therefore developed and is described. This required the determination of the optimal culture medium (commercially available), source of serum supplement, line of myeloma cells, type of culture and routine for the subculturing of the hybridoma cells. The protocol consisted of fusion between immune splenocytes and NS-1 mouse myeloma cells, seeding into the wells of 24-well (24W) plates, culturing in RMPI 1640 medium supplemented with either foetal or donor calf serum, and passaging through 24W plates, 6W plates and 100 ml flasks (20 ml medium), respectively. The time at which aminopterin was added to kill unfused myeloma cells was also critical, with the optimum time being 24 h after fusion. In contrast, the B lymphocyte growth stimulant (2-mercaptoethanol) had no beneficial effects on the growth of the hybridomas.
