(mAbs) is crucial to identifying proteins for proteomic research
However, traditional mAb generation is time-consuming with low efficiency. In this study, we assessed the high throughput method of producing mAbs by immunizing mice with multiple antigens in order to obtain hybridomas against these multiple antigens in one cell fusion. We selected eight proteins that play important roles in human physiological or pathological processes. These proteins were mixed and simultaneously administered to one mouse. We observed the immunizing period for 10 d, and determined the effect of liquid medium and semi-solid medium in hybridoma generation. As a result, all eight immunogens induced antibodies in the immunized mouse in one cell fusion, we obtained hybridomas specific to all eight proteins by enzyme-linked immuno sorbent assay (ELISA) screening, hybridomas against five out of eight showed specific positive in Western-blotting assays.

This indicates that we generated mAbs specific to eight proteins in one cell fusion, greatly increasing the efficiency of mAb generation. Furthermore, we observed that hybridomas selected from the liquid medium and semi-solid medium showed different reactivity to antigens. Our study established high-throughput and time-saving methods for production of mAbs. These results provide alternative approaches for increasing the efficacy of mAb generation.Possibilities of active and passive immunization of baby mice against a S. typhi Antigenen. 14.

These results support annual influenza vaccinations for cancer patients receiving ICIs.

For permissions, e-mail: antibody against or tolerance to the dominant antigen: a model for antigenic could be abolished by passive immunization with antiserum against the dominant antigen (Fc). The induction of tolerance to Fc also eliminated antigenic competition. Anti-Fd production, generally very poor in response to rabbit IgG, was considerably enhanced by these procedures, indicating that it is also subject to antigenic competition with Fc.

A model is proposed to explain antigenic competition which proposes that it is the `co-operative antibody' produced to the dominant antigen which acts as an inhibitor to antibody production to the suppressed antigen by competing for sites —presumably on macrophage membranes—where co-operation occurs. The merits and difficulties of such an Wide use of anticoccidial drugs has resulted in development of drug resistant strains. Current study is based upon the development of egg adapted vaccines; gametocytes, formalin inactivated and formalin inactivated sonicated gametocytes against coccidiosis. Day old chicks (n = 90) were divided into six groups (A-F) with triplicate. On 5th day of age, three groups were orally given developed vaccines (0.2 ml) while on 21st day groups (A-E) were challenged orally with mixed Eimeria spp (60-70,000 oocysts/chick). The comparative effect of vaccines and drug salinomycin was evaluated on basis of different parameters.

Blood, liver and caecal tissues were collected on 5th, 7th and 15th day post infection for indirect hemagglutination test, biochemical analysis and histopathology. Significantly higher body weight gain, feed consumption, mild bloody diarrhea with lowest oocyst count and survival rate of 100% was recorded for gametocytes vaccinated group (P < 0.05). vitamin K2 showed maximum antibodies titer (IgG) in gametocytes vaccinated group.
