Foreword

SN/T 1632 "Enterobacter sakazakii in milk powder exports (Craunot sp) test methods" is divided into three parts. --- Part 1. Separation and counting; Part --- Article 2. PCR method; --- Part 3. Fluorescent PCR method. This section SN/T 1632 Part 3. In accordance with this part of GB/T 1.1-2009 given rule drafting. The partial replacement of SN/T 1632.3-2005 "Enterobacter sakazakii in milk powder test methods - Part 3. Fluorescent PCR method." This section compared with the SN/T 1632.3-2005, in addition to editorial changes, the major technical changes are as follows. --- Modify the standard English name; --- Modified primers and probes; --- Deleted the definitions, terms and abbreviations; --- Increased Craunot genus typing method of identifying species within the informative appendix.

3 Determination

3.1 Method summary Milk powder by enrichment, take enrichment broth added 1.5mL 1mL sterile centrifuge tubes, centrifuged at 5min 8000r/min and gently The supernatant was removed, upside down on absorbent paper, sucking the liquid, different samples should be blotted on absorbent paper in different places; the extract was added 50μLDNA (Thawed at room temperature before use and mix well, fast draw), mix boiling water bath for 5min, centrifuged 5min 12000r/min, whichever is The supernatant was used as a template for PCR amplification of fluorescence, fluorescence was observed in real time PCR instrument curve, so that the milk powder Enterobacter sakazakii (Crowe Connaught sp) rapid test. 3.2 Reagents and materials See SN/T 1632.1.
