Abstract
|
|
|
This study was performed to develop immnoassay method of detecting the residual tylosin and to investigate the residues using HPLC(high performance liquid chromatography) in animal products.
Obtained results are the followings:
1. To develop immunoassay method, the conjugation of activated tylosin tartarate ester derivatives and BSA (bovine serum albumin) was certified at the 290nm of maximal absorbance which tylosin tartrate have.
2. The titration of anti-serum produced from rabbit immunized with the conjugator as an immunogen was too low to analyze the tylosin.
3. The residual tvlosin can be detected by 0.2 ppm using HPLC.
4. Recovery of tylosin from spiked pork samples measured using HPLC was 87.4±4.0%.
5. When the levels of tylosin residues in swine liver and kindney were measured on HPLC. The level was over the maximum tolerance level in one out of ten samples of each organ.
