Indigenous production, characterization and evaluation of polyclonal antibody against Camelus dromedarius immunoglobulin

No diagnostic kits and reagents are available in the market to detect and evaluate camel immune responses to different pathogens. This study aimed to produce sheep anti-camel (Camelus dromedarius) polyclonal antibodies (pAbs) and to determine the specificity with other species immunoglobulin. Immunoglobulins (Igs) from camel serum samples were purified using ammonium sulfate precipitation (40.00% saturated ammonium sulfate). Purity of the camel Igs was tested by sodium dodecyl sulfate polyacrylamide gel electrophoresis. PAbs against (Camelus dromedarius) immunoglobulins were generated by immunizing sheep with purified Igs. Anti- camel Ig polyclonal antibodies titer and specificity were determined using ELISA and Western blot techniques. Polyclonal antibodies specific to camel Igs were significantly high in immunized sheep which confirmed the immunization procedure. PAbs reacted specifically with camel serum immunoglobulin and did not react with other species immunoglobulin of horse and chickens. Polyclonal antibodies produced in this study can be regarded as a valuable tool to be used for immune-diagnostic purposes in camel population world-wide.
