Rec-assay

Hamasaki et al. (1992) reported that monobutyltin oxide, monobutyltin trichloride, and dibutyltin dichloride showed high SOS-inducing potency in the SOS chromotest with iiic/rerrc/rra co/r PQ 37. Dibutyltin dichloride and dimethyltin dichloride were also recognized as producing DNA damage by the rec-assay in Bacillus subtilis H 17 Rec and M45 Rec. Li et al. [Pg.31]

Seven compounds, licoisoflavanone (66), licoisoflavone B (67), semilicoisoflavone B (68), gancaonin C (69), isoliquiritigenin (70), 6-prenyleriodictyol (71), and 8-prenyleriodictyol (72), Fig. (21), showed positive results in the rec-assay. Isoliquiritigenin (70) was most potent of the seven compounds (Table 7). [Pg.225]

Antiarones A and K, brosimone L, cudraflavanone A, and cyclohetrophyllin (53) showed no effect against both M45 and HI7 strains. These data were obtained with spore rec-assay (38 pg of sample/disk). [Pg.231]

Since the respiration of bacterial cells is directly and immediately converted to an electric signal, the preliminary screening of mutagens is possible within 1 h. Moreover, the microbial sensor system employs a homogeneous suspension. Consequently, the sensitivity of the microbial sensor is higher than the "rec-assay". The minimum measurable mutagen concentration is 1.6 jg ml-1 by the microbial sensor and 5.0 /jg ml"1 by the "rec-assay" and 10 p.g ml"1 by the Ames test (26) for AF 2. [Pg.346]

When DNA damage occurs, a number of repair systems can increase the cell s probability of survival. Several assays for genotoxicity rely on indirect measurement of the effects of these repair systems. TWo assays (the B. subtilis rec assay and the E. ooli DNA polymerase assay) measure reduction in the survival of chemically treated cells that lack at least one DNA-repair enzyme, compared with cells that have an intact repair system.198 373...
