Import and export milk and dairy products Tetracycline Residues Radio-receptor assay detection method1 ScopeThis standard specifies the sample preparation and analysis methods radioreceptor import and export milk and dairy products Determination of residues of tetracyclines. This standard applies to milk, milk powder, whey powder tetracycline, oxytetracycline, chlortetracycline, doxycycline screening to detect drug residues.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard. Laboratory use specifications and test methods GB/T 6682 Analysis3 Sample preparation and preservation3.1 Sample Preparation Remove some representative samples from the original sample mix, milk powder, whey powder less than 500g, milk less than 500mL, sharing two Parts, loaded into a clean container as a sample, and sealed and labeled. Sample preparation process should prevent sample contamination or microbial or chemical The occurrence of the change of residue content. 3.2 Sample preservation Dry samples were sealed and stored at room temperature, the liquid sample 0 ℃ ~ 4 ℃ refrigerator to save 5d, or less -15 ℃ can be stored frozen for two months.4 Detection4.1 Method summary Based assay is a competitive receptor immunoreactivity. When the sample contains tetracycline antibiotics, tetracycline antibiotics residues in the sample He was left with a binding site on receptor binding, thus preventing the [3H] labeled tetracycline receptor binding agent sites. Samples Sihuan Su drug content is higher, the competition binding sites, [3H] tetracycline binding to the less marked, measured by scintillation counting with a liquid sample Products in [3H] content cpm value (countperminute, that is, the number of pulses per minute) lower. Samples with residues of tetracyclines cpm value is inversely proportional. 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 tetracycline antibiotics CharmⅡ radioimmunoassay kit (MRLsCompetitiveAssay) 1). pills identified as T. 1) CharmⅡ milk tetracyclines competitive receptor binding test kit is provided by the product under the trade name Charm company. Given this Information in order to facilitate a user of this standard does not imply endorsement of the product. If other equivalent product has the same effect, you can use These equivalent. 4.2.1.1 receptor reagent tablets. the following -15 ℃ cryopreservation. 4.2.1.2 [3H] tetracycline tablets marked. the following -15 ℃ cryopreservation. 4.2.2 Negative control milk. proven antibiotic-free milk. 4.2.3 oxytetracycline standard. 4.2.4 scintillation fluid. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 2309-2009_English be delivered?Answer: Upon your order, we will start to translate SN/T 2309-2009_English as soon as possible, and keep you informed of the progress.
