Percentage of PI, PIP, and PIP2 relative to total phosphoinositides in different cell types
| Cell or tissue | PI | PIP | PIP2 | Number of experiments: |
|---|---|---|---|---|
| Pineal gland | 96.9 ± 1.6% | 0.7 ± 0.3% | 2.4 ± 1.3% | 3 |
| SCG | 96.2 ± 1.2% | 1.8 ± 0.6% | 2.1 ± 0.6% | 4 |
| tsA201 | 96.9 ± 0.9% | 1.5 ± 0.3% | 1.7 ± 0.7% | 7 |
| CHO | 90.5 ± 0.9% | 2.0 ± 0.1% | 7.5 ± 0.9% | 3 |
Measured with post-column infusion of 50 μM sodium formate. Each column includes the sum of all measured species of that lipid. tsA201 and CHO cells were harvested at 85–95% confluency.
