Laboratory use specifications and test methods GB/T 6682 Analysis3 Sample preparation and preservation3.1 Sample Preparation Mixing the original sample was removed from the part of the representative sample, milk powder less than 500g, milk less than 500mL, sharing two charged Jie Net within the container as a sample, and sealed and labeled. Sample preparation process should prevent sample contamination or microbial or chemical residues occur Changes matter content. 3.2 Sample preservation Dry samples were sealed and stored at room temperature, the liquid sample refrigerated at 0 ℃ ~ 4 ℃ save the following 5d, -15 ℃ can be stored frozen for two months.4 Detection4.1 Method summary Based detection is a competitive receptor immunoreactivity. When the sample contains β- lactam antibiotics, sample β- lactam anti- Antibiotic residue in the receptor binding reagent corresponding receptor binding site, thereby preventing the [14C] labeled penicillin G receptor reagent positions Site binding. Samples β- lactams higher the content, the more competitive binding sites [ 14C] labeled penicillin G binding to the less, Measured by liquid scintillation counting sample [14C] content cpm value (countperminute, that is, the number of pulses per minute) lower. Samples β- lactam antibiotic residues is inversely proportional to the amount of cpm value. 4.2 Reagents and materials Unless otherwise indicated, the reagents used were of analytical grade water as a water GB/T 6682 regulations. 4.2.1 milk within β- lactam antibiotics charmⅡ assay kit 1) (MRLSequentialAssay). pills identified as P. 4.2.1.1 receptor reagent tablets. the following -15 ℃ cryopreservation. 4.2.1.2 [14C] labeled pharmaceutical tablets penicillin G. -15 ℃ following cryopreservation. 1) CharmⅡ milk within β- lactam antibiotics competitive receptor binding test kit is provided by Charm products company trade names.
