| Abstract: | Spleen cells from mice immunized with staphylococcal enterotoxin A were successfully fused with NS-1 mouse myeloma cells. Two of the four clones studied produced monoclonal antibodies to staphylococcal enterotoxin A in growth medium which showed titers of greater than 10(6) to 10(7) when tested by the indirect enzyme-linked immunosorbent assay. These monoclonal antibodies showed reactivity with enterotoxins A and E in the enzyme-linked immunosorbent assay. However, the reactivity was higher with enterotoxin A than with enterotoxin E. Nanogram quantities of crude staphylococcus enterotoxin A from Staphylococcus aureus growth were detected by the monoclonal antibodies in electroimmunoblots via autoradiography. |
