3 Sample preparation and preservation

3.1 Sample Preparation Was removed from the original sample portion representative sample should be as fat removed. The edible part of the organization into a high-speed machines are broken Quality, thoroughly mixed, and dividing by quartering a sample of not less than 500g. Load a clean container and labeled markers. Sample number of bacteria in the sample preparation procedure should prevent sample contamination or the occurrence of the change of residue content, for the determination not exceed 106/g. 3.2 Sample preservation The following sample at -18 ℃ preservation, fresh or frozen tissue samples can be stored 72h at 2 ℃ ~ 6 ℃.

4 Determination

4.1 Principle Based assay is the continuity of the receptor immunoreactivity in samples of residual β- lactams and [ 14C] labeled penicillin G, respectively Specific receptor binding of microbial cells. The sample was measured by scintillation counting of [. 14C] Content count value (cpm), the count value with a liquid And sample β- lactams residues in inverse proportion. 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 organization β- lactams assay kit 1). 1) CharmⅡ organization β- lactams assay kit and CharmⅡ liquid scintillation counter is provided by the company's products CharmScience Trade names. This information is given for the convenience of users of this standard does not imply endorsement of the product. If other equivalent products with the same Effect, you can use these equivalent products. 4.2.1.1 negative control concentrated powder. Store at 2 ℃ ~ 6 ℃. When dissolved in water by using 10mL to prepare a negative tissue fluid. Negative group Tissue fluid can be stored at 2 ℃ ~ 6 ℃ in 48h. Such a long time, can be stored frozen at -15 ℃ the following two months, the use of which thawed solution After freeze solution can be stored at 2 ℃ ~ 6 ℃ 24h. 4.2.1.2 MSU variety of antibiotics Standard. stored at 2 ℃ ~ 6 ℃. Dissolved in 10mL of water when used to prepare a variety of anti-MSU Standard antibiotic solution (penicillin G wherein the concentration of 1000μg/L). MSU variety of antibiotics preservation method with standard solutions 4.2.1.1. 4.2.1.3 MSU extraction buffer concentrate powder. dissolving when using 1000mL of water, formulated as MSU extraction buffer, in
