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 Samples frozen at -18 ℃ below.4 Detection4.1 Principle of the method The competition is based on the detected immune response receptors, [3H] labeled and sulfamethazine residues in samples of sulfa drugs and microorganisms Competitive binding was specific receptor on the cell. Was measured by liquid scintillation counting of samples [3H] Content count value (cpm), the count value of In the sample is inversely proportional to the amount of sulfa drug residues. 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 CharmⅡ milk sulfonamides assay kit 1). 1) CharmⅡ competitive receptor binding sulfa milk test kit is provided by the trade name of the company's products Charm.
