Abstract

The aim of this study was to produce chimeric bacterial protein conjugates, to separate them by sodium dodecyl sulphate- polyacrylamide gel electrophoresis (SDS-PAGE) and study their reactivities with human serum immunoglobulins by immunoblot analysis. Universal conjugates: protein LA-peroxidase (SpLA-HRP), protein LG-peroxidase (SpLG-HRP), protein AG-peroxidase (SpAG-HRP), protein LAG-peroxidase (SpLAG-HRP) and protein LAG-anti-IgY-HRP were prepared by the periodate method. In this study, antibodies against the fragment 254-274 from gp120 of human immunodeficiency virus (HIV) were produced in cats, rats and chicken and human samples were used as positive and negative controls in the ELISA. These anti- HIV antibodies developed in animals could be used as reagents in the preparation of diagnostic kits. The ELISA for anti-gp120 antibodies demonstrates that SpLAG-anti-IgY-HRP conjugate is the most universal among available conjugate reagents, which can be used in the immunodiagnosis in both avian and mammalian species.
