1 Scope

This standard specifies the chemical genotoxicity Saccharomyces mitotic recombination test method terminology and definitions, test principle, test side Method, test data and reports. This standard is applicable to the detection of genetic toxicity of chemicals nonspecific DNA (DeoxyribonucleicAcid, DNA) damage Testing.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Mitotic exchange mitoticcrossing-over Usually occurs between genes, but more commonly occurs between the gene and its centromere DNA can produce interactive product sheet Exchange of segments. 2.2 Mitotic gene conversion mitoticgeneconversion A one-way transfer of information sequence within a gene, typically produce non-interactive product.

3 Test principle

In Saccharomyces cerevisiae can be detected in the exchange of mitosis and mitotic gene conversion. Mitosis exchange is produced by colonies homozygous recessive hybrid strain or partially purified recessive gene differentiation colonies tested ; And mitotic gene conversion by carrying two different defective alleles auxotrophic heterozygous in the same gene Measured strains produce prototrophic recovery body. The most commonly used detection of mitotic gene conversion strains have D4 (alleles and ade2 trp5), BZ34 (alleles arg4), D7 (alleles trp5) and JD1 (alleles his4 and trp5). For the determination of homozygous ilv1-92 mitotic gene conversion and reverse mutation can be detected D5 and D7 can produce red or pink There are homozygous fragments mitosis, the two heterologous strains have ade2 complementary allele. Test Method 4 4.1 test substance 4.1.1 Basic information. --- Solid, liquid, vapor or gaseous test substance; --- Chemical properties of the test substance; --- Test substance purity (impurities); --- Solubility characteristics; ......
