Applicant's summary and conclusion
- Conclusions:
- Lissamine Green B failed to induce sex linked recessive lethal mutation in Canton S Drosophila melanogaster and hence is considered to be negative for gene mutation in vivo.
- Executive summary:
In vivo gene mutation assay was performed for the test chemical Lissamine Green B in male Canton-S Drosophila melanogaster by the injection route. Adult male flies were injected with dye in 0.7% NaCl solution at a dose level of 0.0025 or 0.025 M . Alternatively Drosophila larval stages were reared on standard semolina-treacle-agar culture medium containing dye. The positive control for these experiments was ethylmethane sulphonate (EMS), adults having been fed for 72 hr and third instar larvae for 48 hr on a yeasted suspension containing EMS. The frequency of sex-linked recessive lethal mutations in Drosophila melanogaster was estimated by the Basc method. Mutants were scored by mating 12 treated 4-7 day old Canton-S males to Basc females, three females for each male. with successive broods from fresh virgin females at 72-hr intervals. All cultures were maintained at 25 deg C and suspected lethals were checked in the F3 generation. No evidence of recessive lethal mutations was found among the first brood progeny of either adults (0/240) or larvae (0/94) treated with Lissamine Green B and hence it is considered to be negative for gene mutation in vivo.
