International Journal of Pharma and Bio Sciences RAISING OF POLYCLONAL ANTIBODY AGAINST THE ASPERGILLUS ORYZAE PROTEINS IN ALBINO RAT
نویسندگان
چکیده
Aspergillus oryzae is one of the common plant pathogens in wheat, sorghum and other crops. Its toxic activity has been proved. Hence, a sensitive, rapid, and inexpensive screening test to detect Aspergillus in agricultural commodities is necessary to protect human health. Aspergillus oryzae proteins were prepared, characterized, and used as an antigen. 6-month-old white albino rat were immunized by the antigen in combination with Freund’s adjuvant. The antiserum of immunized rat was collected after 35 days. Proteins present in antiserum were precipitated by ammonium sulphate precipitation and purified by dialysis, ion exchange chromatography and SDS PAGE. Immuno blotting analysis was performed to determine antibody specificity towards the antigen. The optimum dilution of prepared IgG was 1:32. Dot strip ELISA test confirmed the presence of specific Antigen-Antibody interaction

Purification of human anti-erythropoietin polyclonal antibodies by precipitation and chromatography as an optimized method with potential application in vaccine studies
Introduction: Polyclonal antibodies are required to be affinity purified. Improved purification methods of polyclonal antibody provide an opportunity to pick the most purified immunoglobulins as a primary or secondary antibody in immunoassays that are included in many vaccine studies. Two common techniques for purifying proteins is salt precipitation and chromatography purification. Our work fo...

Abstract: The aim of the present study was to produce a polyclonal antibody against bovine serum albumin (BSA) conjugated with artemisinin. To gain an immunogenic character of artemisinin, a carboxyl group was added to it using mixed anhydride method. Then, the reactive compound of artemisinin was conjugated with BSA. The BSA+artemisinin were injected to white female New Zealand rabbits for two...
