Table 2. Number of copies of PSD proteins per PSD and their mass contributions (in parentheses).
| 2-min PSD | 15-min PSD | CO2 PSD | |
|---|---|---|---|
| SAP97 | 90 ± 50 (0.8 ± 0.4)* | 90 ± 50 (0.6 ± 0.3) | 120 ± 70 (0.8 ± 0.4) |
| PSD-95 | 320 ± 130 (2.3 ± 0.5) | 540 ± 330 (2.8 ± 1.5) | 730 ± 400 (3.8 ± 1.7) |
| CaMKII | 80 ± 40 (≈6 ± 2) | 170 ± 90 (≈9 ± 4) | 270 ± 80 (≈21) |
For the significance of changes in number of copies, see Results. Number of copies = mass contribution of a protein × average total mass of PSD/molecular mass of the protein, the SD of the number of copies derived from propagation of errors.

Mass contributions expressed as percent (w/w, mean ±SD). The number of copies is expressed as mean ±SD
