Table 1 Comparative analytical characteristics for electrochemical, MTT and fluorescence techniques
Technique | Time | Reagents/Measurement | Effective extract conc. (ppm) | Proliferation effect | LOD(cells/ml |
|---|---|---|---|---|---|
DOX | 40 min. | • No additional reagents • No background signals • No washing needed for the cells | 10 | 120% | 1.25 × 10(4) |
MTT | 4Hrs | • MTT, Acidified Propanol • Washing step required for the cells | 10 | 105-120% | 2.5 × 10(4) |
Fluorescence | 20min | • Syto 24 Green • There is background effect of the solvents and medium | 10 | 120-150% | 2.5 × 10(4) |
