1 Scope

This section SN/T 2497 provisions of the import and export of hazardous chemicals mammalian cells sister chromatid exchange (SCE) in vitro assay Test equipment, test principle, test methods and test results. This section applies to a homologous chromosomal loci and export of hazardous chemicals cause DNA replication product swaps to change the frequency of detection The extent of hazardous chemicals on cells in S phase injured.

3 Terms and Definitions

OECD479 established as well as the following terms and definitions apply to this section. 3.1 Homologous chromosomal DNA replication seat exchange product, the frequency of DNA strand breaks and repair. Principle 4 In dividing cells, each chromosome consists of two chromatids, each chromatid double-stranded DNA. When bromodeoxyuridine Pyrimidine nucleoside (BrdU) as a post-nucleotide precursor substituted thymidine, may be incorporated into the newly copied DNA nucleotide chain. After two After the second copy, two sister chromatids of a double-stranded DNA in the chemical composition have differences. One from single-stranded nucleotide chain containing BrdU Composed of DNA, and the other by a single double-stranded DNA nucleotides contain BrdU composed. With Hoechst33258 staining, The former color depth, which is a light color. When switching between the two allelic chromatids occur, according tucked inside each chromatid different shades Stained fragments are identified.

5 Apparatus and reagents

--- BrdU-containing medium; --- Colchicine colchicine or amine; --- 0.25% trypsin solution; --- 2 × SSC solution (i.e., 0.3mol/L sodium chloride and 0.003mol/L trisodium citrate); --- 3% Giemsa solution (pH 6.8 phosphate buffer solution); --- Incubator. ......
