Percentage distribution of subpopulations of the heterogeneous S. epidermidis strains in electrophoretic mobility at pH 2 and their isoelectric points (IEP)
| S. epidermidis strains | Subpopulation #1 | Subpopulation #2 | ||
|---|---|---|---|---|
| IEP | Size (%) | IEP | Size (%) | |
| 45B | 1.5 | 44 ± 10 | 2 | 56 ± 10 |
| 196B | <1.5 | 78 ± 5 | 2 | 22 ± 5 |
| 493B | <1.5 | 26 ± 4 | 2 | 74 ± 4 |
| 906B | 1.5 | 85 ± 4 | 2 | 15 ± 4 |
| 1098B | 1.5 | 82 ± 4 | 2 | 18 ± 4 |
Subpopulations #1 represents the more negatively charged population, while subpopulation #2 represents the less negatively charged population. The population sizes are mean ± SD over three independent experiments
