TABLE 3.
Coefficients of variation (CV) of the As389/HHQ-BSA ELISA run in MH culture broth diluted 1/5 using representative concentrations at a low, medium, and high concentration range (IC20, IC50, and IC80)
| Reproducibility conditions | IC | Mean | Desv. est. | % CVa |
|---|---|---|---|---|
| Interday | 20 | 26.71 | 3.36 | 12.6 |
| 50 | 4.32 | 0.89 | 20.6 | |
| 80 | 0.73 | 0.26 | 36.2 | |
| Interplate | 20 | 25.72 | 3.91 | 15.2 |
| 50 | 2.87 | 0.56 | 19.5 | |
| 80 | 0.32 | 0.12 | 37.5 | |
| Intraplate | 20 | 24.34 | 3.35 | 13.8 |
| 50 | 2.75 | 0.27 | 9,9 | |
| 80 | 0.29 | 0.04 | 13.9 |
The coefficient of variation (CV) was calculated following the equation CV (%) = σ/μ × 100. The results were obtained by measurements performed in either triplicate on the same ELISA plate (intraplate), made on three different days (interday), or by analysis on three different plates (interplate). The concentrations of the replicates, mean, standard deviation, and ICs are expressed in nM. IC: inhibitory concentration; R: replicate; σ: standard deviation; μ: Average.
