Abstract: Using spectinomycin (SPE), carboxyl methyl hydroxylamine hydrochloride （CMO）， glycol diglycidyl ether （EDE）, bovine serum albumin (BSA) and ovalbumin （OVA） as the main stuff, four artificial-immunogens had been obtained by the N-hydroxysuccinimide-activated ester method and the EDE double functional group method. Ten female rabbits were immunized with this two artificial-immunogens. Animal immune test demonstrated that there were antibodies against SPE in rabbits sera. The polyclonal antibody was measured with indirect ELISA test. The titer was 1∶160000 and the IC₅₀ was 0.484 ng/mL. This study laid the basis for further research on the immune test kit for the SPE remnant.
