چکیده انگلیسی
In this work, three unreported immunizing haptens of ractopamine (RAC) were synthesized and used to produce highly sensitive and specific polyclonal antibody. The spacer arms of haptens for coupling to protein carrier were located on different position of RAC with different length. High affinity polyclonal antibodies were obtained and characterized in terms of titer and sensitivity by using enzyme-linked immunosorbent assay (ELISA). The best antibody employed in a heterologous competitive ELISA exhibited an IC50 value as low as 0.12 ng mLâ1 and could not recognize other 10 β-agonists including clenbuterol and salbutamol. The heterologous competitive ELISA was preliminary applied to swine urine and the results showed the new antibody was sufficiently sensitive and specific, and potentially used for the detection of RAC at trace level in real samples.
