1 Scope

SN/T 2497 provisions of this part of the import and export of hazardous chemicals and materials Reagents NorthernBlot experiments, the main instrument Equipment, test procedures and results analysis. This section applies to the detection of gene transcription import and export of hazardous chemicals caused abnormalities. 2 terms, definitions and abbreviations 2.1 Terms and Definitions The following terms and definitions apply to this section. 2.1.1 It can react with a particular nucleotide sequence complementary to specific hybridization, hybridization and then be detected by methods known specific labeled nucleotide chain. 2.2 Acronyms The following abbreviations apply to this section. 2.2.1 MOPS3- (N- Marlene) propanesulfonic acid 2.2.2 RNA ribonucleic acid Principle 3 Under denaturing conditions RNA samples to be tested by agarose gel electrophoresis separation, according to their position in the gel and then transferred To nylon membrane or nitrocellulose filter membrane, DNA, or RNA probe immobilized before or other marker isotope labeled hybridization and Autoradiography. If the probe sequence complementary to the analyte contained, both by the principle of complementary base binding, thus demonstrating the RNA fragments to be detected and their relative size.
