Table 1. Density of HER2 labeling per morphological cell type.
A total of 11 SKBR3 cells were studied including two flat cells. Data of a test sample containing randomly distributed QDs are also indicated. The information includes the number of images in an experimental group Nimage, the number of all QD labels in a group Nlabel, and the average label density ρ.
| Cell group | Nimage | Nlabel | ρ (μm2) |
| All cells | 112 | 14,171 | 26.9 |
| Ruffled regions | 80 | 10,870 | 30.5 |
| Homogeneous regions | 32 | 3,307 | 19.3 |
| Ruffled cells | 90 | 10,513 | 28.8 |
| Flat cells | 22 | 3,664 | 22.6 |
| QD random | 24 | 4,506 | 41.2 |
