Immunoevaluation and Characterization of Tetanus Toxoid by using Natural polymer as an adjuvant
Journal Title: National Journal of Integrated Research in Medicine - Year 2010, Vol 1, Issue 5
Abstract
Natural polymer like potato starch is a mixture of amylose and amylopectin, . Extraction of Potato starch was performed by rasping, centrifugation, refining and drying method. In our research method, we employed potato starch as a biodegradable polymer; It has a great impact on pharmaceutical applications due to its bioavailability, non toxic, high change density and biodegradability. In our research work, we have selected Potato starch polymer as a model of immunomodulatory effect of vaccine of tetanus antigen. According to WHO, Tetanus is a systemic infectious disease caused by genus Cl Tetanii. It has been estimated that the tetanus fever endemicity among large populations and global emergence of multidrug resistant strains to impose greater urgency on the evaluation of existing and new vaccines to prevent mortality of neonates and in pregnancy. Recently available recombinant vaccine was seems to be side effect and cost effective. The starch polymer in the form of microspheres was preferred in order to replace the alum to elicit sustained immune response because alum induces local granuloma and hypersensitivity reaction to some individual. We have employed microencapsulation technique by using 0.5% ml glutaraldehyde as a crosslinking agent. The particle size was analyzed as 40.23µm. Invitro studies was analyzed by SEM, stabilities studies Immunogenicity studies was carried out by incubating the sample, centrifuged and tested for an antigen and the Compatibility study was performed by Infrared Spectroscopy, the antigen integrity was studied by SDS PAGE and ELISA. Immunoglobulin titer values was found out ( IgG, IgA,IgM, IgE) to show the increase level of antibody response.
