چکیده

A high-throughput Serum Bactericidal Assay (SBA) was developed to monitor the functional antibody responses to capsular polysaccharide antigens from multiple serotypes of Neisseria meningitidis. This assay measures the ability of an antibody, aided by complement, to mediate killing of bacteria. Functional assays of this type are increasingly used in the quality control arena as potency release tests. Consequently, there has been an enhanced requirement for reproducibility in the performance of this type of assay. Assay validation is, therefore, important to facilitate understanding of the significance of values obtained, and to enable appropriate and informed use of the assay. This study involved the evaluation of the high-throughput serum bactericidal assay including the effects of different dilution and transfer techniques on assay performance. The results presented here demonstrate the repeatability, and the precision and ruggedness of the assay.

Effect of IL-2 co-expressed or co-inoculated with immuno-dominant epitopes from VP1 protein of FMD virus on immune responses in BALB/c mice

Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...

Strong Immune Responses Induced by a DNA Vaccine Containing HPV16 Truncated E7 C-terminal Linked to HSP70 Gene

Background: Vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. DNA vaccines are attractive tools for the development of HPV vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. However, there is a need to increase their potency b...

Comparison of Immune Responses following Intradermal and Intramuscular Rabies Vaccination Methods

Rabies is a zoonotic viral disease. The causative agent is a negative-sense RNA genome virus of the genus Lyssavirus (Family: Rhabdoviridae). The disease, commonly transmitted by rabid dogs, is the cause of mortality of over 59000 humans worldwide annually. This disease can be prevented before the development of symptoms through proper vaccination even after exposure. Hence, improvement of the ...
