title: Immunoglobulins of camel (Camelus dromedarius) colostrum.
abstract: Immunoglobulins G, M and A were identified in dromedary camel colostra by acid precipitation, gel filtration and fast-protein liquid chromatography (ion exchange). Heavy and light chains were identified by polyacrylamide gel electrophoresis and Western blotting. IgG subclasses (IgG1, IgG2 and IgG3) were isolated by DEAE ion-exchange chromatography and shown to have different electrophoretic mobilities. Cross-reactivity of camel IgA with IgA of other species was determined by enzyme-linked immunosorbent assay (ELISA). Most of the immunoglobulin content was IgG, but a molecule identifiable as IgA was detected and purified. It would appear that in the camel, as in cattle, IgG is the major secretory immunoglobulin of colostrum.
