Fig. 2From: Development of an indirect ELISA for detecting humoral immunodominant proteins of Mycoplasma hyopneumoniae which can discriminate between inactivated bacterin-induced hyperimmune sera and convalescent seraOptimization of ELISA working condition. a The optimal concentration of antigen was the bacterial lysates of fusion protein and free GST protein without dilution. b The optimal blocking buffer was PBS comprising 10% FBS and 2.5% skimmed milk. c Both hyperimmune serum and convalescent serum with dilution of 1:500 and HRP-labeled rabbit anti-pig IgG diluted at 1:20000 were the working concentration of primary antibodies and secondary antibodyBack to article page
