1. Methyl green ("ethyl green") C. I. Number 685 was examined and found to behave identically with methyl green C. I. Number 684 (no longer available) in respect to molar extinction coefficient, effect of combination with polymerized DNA, failure to react with depolymerized DNA, and effect of pH. 2. The mass law permits the calculation of P/dye. This is found to be 13 P/dye. The same value is o...

a novel, simple and more sensitive spectrophotometric procedure has been developed for the determination of brilliant blue fcf and carmoisine in food samples by an aqueous two-phase system (atps). after extraction, the absorbance values were measured at 527 and 632 nm for carmoisine and brilliant blue fcf, respectively. the effects of different parameters such as, polyethylene glycol (type and ...

OBJECTIVE Application of on-spot staining with brilliant cresyl blue, a supravital stain, was investigated in fine needle aspirates from breast, lymph node and thyroid. STUDY DESIGN Patients with palpable breast lumps, lymph nodes and thyroid nodules were included in the study. Brilliant cresyl blue was used to stain the smears, which were evaluated for smear adequacy as well as cytological d...

The suitability and selectivity of nutrient broth with bile salts and varying concentrations of brilliant green as an enrichment medium was tested for the isolation of Plesiomonas shigelloides from faeces. The broth was most effective at a concentration of 0.001 g/l brilliant green, using faeces deliberately contaminated with Plesiomonas. Two hundred and nineteen faecal samples from Nigeria wer...
