Immunization procedure-related immunoglobulin levels in the development of antibodies against Cysticercus cellulosae.
Various immunization procedures were investigated in an effort to improve the number of hybridomas producing antibodies against Cysticercus cellulosae. Ten groups of 5 BALB/c mice were subjected to different immunization procedures and were bled repeatedly over a period of 68 days. The samples of sera thus obtained were tested by enzyme linked immunosorbent assay: total immunoglobulins, IgG and IgM levels were determined. In general, total anticyst antibody titres increased during the course of immunization but in 3 groups the final titre was lower than the maximal antibody titre. Overall, immune tolerance did not appear to be a problem and longer immunization programs seemed to end with slightly higher antibody levels. So far, 4 mice from the group that exhibited the highest immunoglobulin levels have been used for hybridoma production. Out of 124 hybridomas thus obtained, only 1 secreted antibodies against Cysticercus cellulosae.
