Return to HaCaT keratinocytes

Summary Table

The estimated AA levels in HaCaT keratinocytes (unstimulated, A23187 (5µM), COX inhibited and A23187 (5 µM), ATP (2 mM) and UVR (15 mJ/cm2)) for 0.5, 1, 3 and 6h. Analysis was performed using GC-FID. Results are expressed mean ± SD (ug/106 cells) of three independent experiments.
